WE HAD FRIENDS THAT DID EXCURSION THING AND THIS IS THERE RECOMENDATION " THE BEST WAY TO DO TOURS SOUTH IS BOOK A PRIVATE TRANSFER (USA Transfers) YOU GET THERE HOURS B4 ALL THE BUSES HAVE THE PLACE TO YOUR SELF AND LEAVE WHEN YOU ARE READY, BEAT ALL THE TRAFFIC BACK TO CANCUN . IT IS WORTH EVERY PENNY. BEST IF YOU CAN GET 2 OR MORE COUPLES." GLENN:aktion033:
