I am looking for an all-inclusive resort that has on-site activities for older kids...ocean/lagoon/river kayaking, or rock wall, or adult pool slide...stuff like that. Just came back from the Omni in Cancun and it was great..but had to walk a half mile down the road to get to the non-motorized water toys...and there was no beach at that area. That was OK, but there has to be a place somewhere in the Caribbean/Mexico that has the water activities or activities for older kids/young adults right at the resort! Any ideas? Thanks in advance!!! Looking to go somewhere this August.
