Puerto Rico is one of the Caribbean's cheaper destinations, but there's no limit to what you can spend if you're in a party mood or on a gambling binge. It's possible to travel very comfortably on around US$250 a day, staying in ritzier hotels and eating three meals a day in decent restaurants. A moderate guesthouse-and-diner budget would slip somewhere between US$150 and US$200, while budget travelers can get by on less than US$100 a day by bunking up in no-frills hotels, eating at local food stands and taking public transport in preference to hiring a car. Note that accommodations are cheaper in the May through November low season. All major credit cards and traveler's checks are widely accepted and there are plenty of ATMs should you prefer to access your home bank account directly. Once you leave the cities and touristed areas, it's best to carry cash.

The US dollar is sometimes referred to as the peso. Tipping follows North American rules. Restaurants usually include the service charge in the bill, but if they don't a 15% tip is expected. Some hotels add a 10% service charge, otherwise an equivalent tip is expected. There's a government tax of 7-10% on hotel rooms and some hotels charge an energy surcharge of around 3%. These extras can really add up - find out what you're in for when you make your booking to save a nasty surprise at settle-up time. Bargaining isn't common except in artisan markets where you can probably wrangle a discount.
