FANTASTIC input - ALL of it..thanks !

Will certainly try the various restaurants and the Hammock House sounds great on Friday night (Thanks Scubalover !)..Ziplocs are also something we hadn't thought of but will take for the myriad of uses mentioned...again, ALL GREAT FEEDBACK ! (This board is PHENOMENAL when compared to other msg boards..it's amazing how OFTEN people post here vs. other boards..thanks again to all who replied !

Two other questions..

1) What's the voltage and outlet-type at Costa Maya..will we need adapters ?

2) Any suggestions on what tours to take ? We both like history and wildlife so we thought the boat ride through rainforest to ruins would be great..any thoughts/feedback on this tour,the cave tubing tour, or others ?
