I've never dove with Alison but hope to some day; she has an excellent reputation. I did however dive with Dressel on both of my stays at the Iberostar and frankly other than the fact they are a bit overpriced they treated me quite well. I had enough experience that I was always grouped with other divers & a DM that all knew what they were doing & we dove our tanks (on the morning dives) rather than a time table. Afternoon dives are timed due to time limitations due to the schedule plus the same DM's from morning dives do the afternoon dives.
One of the benefits of using Dressel is that they are so close to the reefs that the boat return to the resort after the 8:30 dive allowing a late breakfast, or a second one on most days. This also allows a bathroom break etc, as you have 20 or more minutes between arrival & departure for the second dive of the morning. One other benefit is that they have an assortment of boats so on those days when the winds are up and the small boats can't leave the harbour Dressel may still be taking divers out.
A downside is that you pay up front, and larger dive packages lower the price, but NO REFUNDS. If you can't complete the number of dives you've paid for you get a credit note for use on another trip, which I assume will be usable at any Iberostar resort that has a Dressel Dive Shop. To the best of my knowledge that is still the policy, but I may be wrong so ask if considering a multi day package. You can book & pay on line and it used to get a 15% discount, and I always received a 10% discount for cash. No discounts for credit cards, and they weren't very flexible on prices even with a 20 tank package & cash.
