One one thing to note- beach clubs in Costa Maya are generally VERY close together especially around the center area of malecon. They may be literally separated by a rope or change of  loungers, color etc.    El Faro is immediately to the right of Tropicante (looking at the water). Suggest you check out the T-shirt logo of your sever, and ask for a menu and take photo before you order - so again you can check you are at the right place and have prices and descriptions to hand.
