I was bit skeptical as they only accept cash. I like the small boats and 8am dock pick-up though.
Nothing to be skeptical about. Many ops either require cash or offer a cash discount. DWM is as solid as any operator (more so than many) on the island and I believe is one of the longest operating ventures on the island. Not only do the offer free rental of basic equipment, small boats, and excellent DM's, but they are a favorite op of several scuba shops in my area. We dove with them on our first trip to Coz several years ago and would not hesitate to dive with them again. We dive with someone else now mainly for bigger tanks and more convenient tomwhere we stay, but DWM is a great operation. They would not have been around as long as they have if they weren't.
Safe travels and please drink a Bohemia Obscura for me.
Merry Christmas,
