I could use some words of wisdom on four dive sites in Cozumel. I'll be making a two day trip to Cozumel and will be diving with Scuba Du. They have scheduled dive spots for the week. Wednesday is Columbia Wall and La Francesa, Thursday is Palancar Bricks and Yucab Reef. I will be with a group novice divers and we want the best diving possible in four dives, but don't want any too advanced for a bunch of newbees. Would these dives spots be a good choice?
