Food is inexpensive. There are a very large number of Italian restaurants. No trip to Margarita is complete without trips to Porlamar for dinner and shopping. We strongly recommend that people get tans before going to Margarita as the sun is very intense. It's a good idea to bring a Lycra rash guard to keep the sun off your shoulders.
Some people occasionally wear shorties but usually more for sun protection than warmth.
Booties are advisable as there are some sea urchins in the occasional kelp beds. Most locals don't wear booties but we think it's a good idea. Gloves are also not a bad idea, especially if you keep a tight grip on your booms. Bring a rashguard. They generally chill you but you might want it for sun protection.
