Got back from AC last Monday. It was great, went to many of the restaurants recommended by your msgs.My advice: BRING A SLEEP MASK! The sun is so bright & beautiful, it will wake you up at sunrise (even with the drapes closed)! Also, pack some clothing in yr hand carry luggage (ours was delayed for 24 hrs).Patojo Scuba at Tides Beach Resort is terrific. They have a resort course for non-certified people (cost $100 US) and you can scuba dive with them yr entire stay. If you go to Altun Ha tour bring extra $$ for spa treatment--mood mud felt primitive & relaxing. Happy Traveling
