Just returned from Coz and Hotel Coz yesterday. First trip to the island. The walk to town isn't bad. Probably 15 minutes is correct. We typically took a taxi into town and then walked home to work off some of the great food...try the Mission, Prima, and Guidos...Hotel was great in a kind of love boat way, the entertainment staff play water volleyball and such for the non-divers and do a floor show each night that isn't great, but is fun. Diving is easily accessable across the street. Breakfast is great, but by the end of the week I was tired of it. I'm going back for 2 weeks in January and look forward to again being at hotel coz. Oh, go down the street, next to the Barracuda Hotel, for dessert at the little cafe (on the downtown side of the Barracuda, can't remember the name) amazing pies and milkshakes.
Diving was impeccable, some long drifts in good current, some not so much. Saw plenty of turtles, a couple of nice rays, morays etc...coral is great, but really overblown with sand in some places.
Enjoy the trip,
Dave
