Puerto Rico operates on the US dollar, which removes currency exchange considerations for American travelers but means costs align with US mainland pricing structures rather than typical Caribbean tourist economies. The island functions as a hybrid market where certain goods match stateside prices due to shipping regulations while services and local production remain cheaper. A 2023 Bureau of Labor Statistics comparison placed San Juan's cost of living index at 86.3 relative to New York City at 100, but 112.7 relative to the US national average, making it more expensive than most mainland cities outside major metros. The Jones Act of 1920 requires all goods shipped between US ports to use US-flagged vessels with American crews, which increases consumer prices for imported items by an estimated 15 to 20 percent according to a 2012 Federal Reserve Bank of New York study. Hurricane Maria in September 2017 damaged significant portions of infrastructure and agricultural production, creating lasting price effects in construction materials, electricity costs, and locally grown food that persist through current pricing.
Accommodation costs vary dramatically between San Juan's tourist corridor and the rest of the island. Condado and Isla Verde hotels in San Juan range from 150 to 400 dollars per night for standard rooms during peak season from December through April, with rates dropping 30 to 40 percent during hurricane season from June through November. The Caribe Hilton, which opened in 1949 as Puerto Rico's first luxury hotel, charges between 250 and 500 dollars nightly depending on season and room category. Outside San Juan, guesthouses in Vieques or Culebra run 80 to 150 dollars, while paradores—government-certified small hotels promoting local tourism—average 70 to 120 dollars nightly. Vacation rental properties through platforms have proliferated since 2015, with entire apartments in residential San Juan neighborhoods like Santurce or Miramar available for 60 to 100 dollars nightly, though rental regulations enacted in 2019 require minimum seven-night stays in some residential zones. The isla's short-term rental market expanded significantly after Maria when property owners converted damaged homes into tourist accommodations rather than pursuing residential repairs.
Food costs split into two distinct markets. Restaurants in Old San Juan's tourist areas charge 18 to 35 dollars for entrees, with Marmalade Restaurant and Santaella representing the higher end at 28 to 45 dollars per main course. The same dishes at local establishments in neighborhoods like Río Piedras or Caguas cost 8 to 15 dollars. Mofongo, the mashed plantain dish that serves as Puerto Rico's most recognized plate, ranges from 12 dollars in tourist restaurants to 6 dollars in local spots. A full lechón asado meal at roadside chinchorro stalls along Route 184 through Caguas costs 8 to 12 dollars with rice, beans, and plantains. Supermarket prices at chains like Pueblo or Selectos run approximately 20 percent above mainland equivalents for packaged goods due to Jones Act shipping costs, with a gallon of milk at 5.50 to 6 dollars and a dozen eggs at 4.50 to 5.50 dollars based on 2024 San Juan metro pricing. Local produce at Plaza del Mercado de Santurce or Placita Roosevelt costs less, with plantains at 1 to 1.50 dollars per pound and local avocados at 2 to 3 dollars per pound. The coffee shop culture charges 3 to 5 dollars for local Puerto Rican coffee drinks, comparable to mainland prices despite the island producing its own beans in the Cordillera Central region.
Transportation costs depend entirely on rental car versus public transit choices. Rental cars from San Juan's Luis Muñoz Marín International Airport start at 35 to 50 dollars daily for economy vehicles, climbing to 250 to 400 dollars per week, with prices doubling during peak holiday weeks. Gas prices in 2024 average 3.80 to 4.20 dollars per gallon, roughly 30 cents above mainland US averages due to shipping. The island measures 100 miles east to west and 35 miles north to south, making a full tank sufficient for most cross-island trips. Público vans, the traditional shared-taxi system, charge fixed routes at 1.50 to 5 dollars depending on distance but operate on inconsistent schedules that make them impractical for tourists on tight timelines. The Tren Urbano metro system in San Juan covers 10.7 miles between Bayamón and Santurce with single rides at 1.50 dollars, but the system opened in 2004 and serves limited tourist destinations. Taxi rides within San Juan cost 12 to 25 dollars for typical routes, with airport to Condado running 15 to 20 dollars. Uber and Lyft operate in San Juan metro with similar pricing to mid-sized mainland cities. Ferry service from Ceiba to Culebra or Vieques costs 2.25 dollars each way per passenger and 19 dollars for vehicles, but the cargo-passenger ferries often sell out days in advance during peak season, and the departure point moved from Fajardo to Ceiba in 2018 following Maria damage.
Activities and entrance fees remain modest compared to accommodation. El Yunque National Forest charges no entrance fee but requires advance recreation.gov reservations during high-demand periods. The 28,000-acre rainforest, designated as a National Forest in 1903 and the only tropical rainforest in the US National Forest System, offers free access to trails and waterfalls. Castillo San Felipe del Morro and Castillo San Cristóbal, both components of San Juan National Historic Site managed by the National Park Service, charge 10 dollars for a combined ticket valid seven days, with free entry for US citizens under 16. The fortifications began construction in 1539 and 1634 respectively. Bioluminescent bay tours to Mosquito Bay in Vieques, recognized by Guinness World Records in 2006 as the brightest bioluminescent bay globally, cost 50 to 75 dollars per person for two-hour kayak tours. Snorkeling equipment rental at Flamenco Beach in Culebra runs 15 to 25 dollars daily. The Arecibo Observatory, which operated the world's largest single-aperture radio telescope at 1,000 feet diameter from 1963 until its collapse in December 2020, charged 12 dollars admission before closure; the visitor center remains closed as of 2024 while authorities debate reconstruction. Museo de Arte de Puerto Rico in Santurce charges 6 dollars for adults, 3 dollars for children and seniors. Camuy River Cave Park, showcasing one of the world's largest cave systems carved by the Camuy River, charges 20 dollars for adults, 14 dollars for children for guided tours through portions of the 268-acre park.
Sales tax applies at 11.5 percent in San Juan, combining a 10.5 percent state sales tax with a 1 percent municipal tax, among the highest rates in any US jurisdiction. Other municipalities charge 11.5 percent or 10.5 percent depending on local ordinances. Hotel occupancy taxes add 7 to 9 percent to room rates, varying by property size and municipality. Tipping follows mainland US customs at 15 to 20 percent for table service, 1 to 2 dollars per drink at bars, and 15 to 20 percent for taxi rides, though some restaurants automatically add 18 percent gratuity to bills. Resort fees at beachfront hotels add 25 to 45 dollars daily for amenities like beach chairs, pool access, and internet that would be included in the base rate at properties elsewhere. These mandatory fees appear separate from quoted room rates, inflating actual costs.
