I was going to do this as well but I read that they give each guest a full blown map of the resort when they check in. Sure enough, they were right! So if you want to save money then don't bother with the maps since they're provided.
A few ladies have asked about reception locations. My best advice is to go with the beach reception. Especially if you're not having your ceremony on the beach & in the sand. Give your guests a true "beach" wedding and go for feet in the sand We had 40 guests and the best option was the beach in front of Pelicanos. It was large enough for the whole party. The other 2 beach locations are nice but are a bit smaller so if you have a smaller party they'll work too.
