I don't know if it will help (although it would it many others join in) but it still made me feel good sending the following to both email addresses:
Dear Sir;
My wife and I are planning a trip to Cozumel for later this year. In reviewing brochures with our travel agent and examining various websites, your property seemed ideal. My wife, being a non-diver, wants an all-inclusive property such as yours to keep her occupied during the day when I dive. I, in turn, appreciate a few cold cervesas to chase away the salt water.
Recently, however, I have been reading comments on ScubaBoard that the hotel is charging for other dive operators to pick up hotel guests from the dock. It appears that the better dive operators are not going to pay this fee and will refuse to pick up from the Iberostar. Since I have my preferred dive operator in Cozumel (and choose not to dive with cattle boat operations) it will mean that I must make my way to the Caleta to meet my boat. That will cost me an extra $20.00 daily and be a major inconvenience.
So, in spite of how attractive your property looks, I cannot follow through with any booking until such time as you change this policy. If you don't mind helping me, perhaps you can recommend an all-inclusive in Cozumel whose senior management is not so short sighted and doesnt charge this fee?
