Hi,
I don't know anything about play del sol, but I do know that Mr. Sancho's is wonderful. There is so much to do there, horseback riding, atv rentals, small shops, restaurant (you can eat outside on the beach or inside...still open..only one wall). There is a large hot tub, water trampoline for kids. There is a locker area. Very, very clean bathrooms and shower area.
The food is delicious. The servers are very nice, very funny.
We loved it and would definately go back again. We were there for three hours, hubby and I. The only reason we left, is because we had never seen cozumel before, so we wanted to allow ourselves plenty of time for shopping..lol. Next time we will stay longer.
You can check it out at mrsanchos.com. We highly recommend this place.
