I don't know where the $300 figure comes from, it was $140 cheaper per day for my wife and I to dive, and with 5 days planned, it was $700 saved by diving with AS. We have stayed at 5 different properties on Coz, some multiple times, and Coz Palace was definitely the nicest of the ones we have used. I don't know of any nicer properties without going down to the south end of the island, which I don't like. We go downtown almost every day when we are in Cozumel, and we can walk there and back from the Coz Palace. It is a 25 to 30 minute cab ride from the south end to the downtown, and I don't want to be that far away. There is no "perfect" accommodations or dive op, but I felt like we received pretty good value for our dollar.
