I am not sure where you are traveling from but if Continental is your provider, we have a code that you can input that will give you 3 to 5 percent off airfare ;-) The challenges start on August 19th..and we have a filming crew joining us to shoot a pilot film to give divers and idea of how fun the Ultimate Diver Challenge will be next year. The challenges evaluate buoyancy, navigations, search, stress, rescue skills, underwater mapping, fish knowledge and identification along with general knowledge of the safety of diving. Let us know if you need accommodations...we do have aggreements with some excellent pricing for the week...Most of us are staying at the Reef Club and Hotel Cozumel... Pam
