Does anyone on the board have any recommendations for hotels in Playa del Carmen and Cozumel?

I need a cheap hotel on or very close to the beach; there will be 3 of us in the room so it needs 2 beds.

We're heading to Playa on the 17th, 18th and 19th and then Cozumel on the 20th and 21st before heading to Chicago on the 22nd.

Found out it's much cheaper to fly from Cozumel than Cancun.

Thanks all...

Simon...
