I have never had a bad experience with any of the servers or room attendants that we have had. I'm in a service industry and understand how demanding people can be. I think with Disney there is an expectation of service and it is usually met or exceeded. In fact I had one server on one of our cruises notice that my one of my daughters kept ordering the same thing and he asked why, it was a baked potato plain, I told him she has severe heart burn, he was a doctor in his home country and gave us some helpful pointers on how to combat the problem with natural things, she continues to use some of these helpful hints. Who knew that going on the Disney Cruise could lead to us finding these helpful hints.
