I'm sure it will be OK, but if you want to post a thong picture (not topless, it is a family site), we could better judge the reaction on the beach.

Please do read this site, plan to get out of the resort and explore. Watch some of the webcast announced on here, schedule on realnegril.com.
Then plan to attend a few while there. Ask questions here, have fun and tell us about it when you get back.
