It’s more of the uncertainty aspect, it’s more the diving may or may not go that is having us consider changing plans. We really have zero desire to bum around the hotel/island/beach, so if we switch to the cenotes we have a 100% chance of diving. With the later morning cancels from the island dive shops they are somewhat mutually exclusive, we can either get the first ferry and get 2 cenotes dives in or we can roll the dice here and get 0, 2, or 4 dives. It’s no ones fault but we have exactly 0 desire to be idle.
I understand - Get on the ferry, grab a cab, call or message dive shops over there while you're on the way - someone will take you diving!! Whatsapp is the way we make calls here and of course Facebook.
I'd hope the weather chills out and the wind shifts to make your week easier.
