We are planning to visit Cozumel the middle of August to dive and hopefully help with some turtle rescue/releases. Last summer we had no problems with flights but just discovered that Delta only does Thursday, Friday and Saturday flights into Cozumel. I will be traveling with my son and he has in-service where he teaches starting 8/23 and has to be there. My anniversary is the 11th and want to be home with my husband for that so we don't have too many choices. I wanted to come down Sunday the 12th and return Wednesday 8/22. There are no flights out the 22nd. We could do 12 - 19 but really want to stay longer especially since no one knows when the turtles will start hatching.
I know many people save money by flying in and out of Cancun and taking the ferry to Cozumel. We have scuba gear and my son has 2 bags of camera gear plus regular luggage so the thought of doing the ferry and getting to the airport does not excite me.

I imagine we could get an early ferry and get to the airport for a 1:15 flight. There are no late flights for us. But what is the best way to get to the airport???
My other thought would be to take the ferry to PlayaDeCarmen on the 21st and stay at a hotel that night, sleep in and go to the airport late morning.

I looked into using Delta going down and another airline back from Cozumel but the one way fares are the same price as round trip. And I have perks on Delta and we just prefer them.

Looking for an suggestions.
is this workable?
are there any reasonably priced hotels close to the ferry terminal in Playa?
any suggestions for transportation to the airport from Playa.
How often do the ferries cancel because of bad weather. I know that Cozumel's marinas close if conditions are bad and no boats go out for diving. That is another reason to go over a day early.

thank you so much for any help you can give me.
