Many shops have divers from other countries besides Dressel. I can tell you that the DMs from foreign countries there know the reefs very well having dove there for many years. Aldora has DMs
from foreign countries. If you want to knock Dressel, do so, but be fair about it.Their full time DMs are very, very experienced. I've dove in many parts of the world-Egypt, Thailand, and Belize, and dove with excellent DMs who were not from the local country.
You said you had no choice. You do have a limited choice. Their prices are cheap, they offer free nitrox and free dive courses . You pay for the course, but not for the dives. I just dove at Aldora, paying top dollar to get dive choices. I had 25 dives. How many days did I get a choice? 2 of 10. The first and the last only. I dove Cedral 6 times and Yucab 5 times.I got no choice at all the others.
