We'll be in Cozumel on Friday, Sept. 6 from 8-5. It'll be me, hubby and our 7 and 9-year-old kiddos. I've narrowed our search down to Xel-Ha, XPlor, Chankanaab and Secret River--we're cruising NCL and would book through them. Any suggestions would be SO appreciated! Is there something we should consider that I haven't thought of? We were in Cozumel last year and booked a fantastic snorkel/ beach day, but it's not available this year. FYI- kids love animals and have zip-lined some, but aren't super-crazy thrill-seekers. Thanks! :)
