wenlitz-
Kudos for following your instincts - but too bad that you weren't able to get them resolved while you were AT WDW. In several guidebooks (Unofficial Guide being one), they say that it is often tough to get any sort of compensation/solution after the fact at Disney, and that seems as if it is the case with you.
Last year, DH and I booked a quick weekend trip at BC for the Food and Wine festival - we booked under a code and got a rate of $229 (I believe) for a waterview room - I asked CRO to put under myreservation that if a standardview room under the same rate code became available, to please switch us over, as that would have been $189 a night.
We arrived at midnight, and we were given a room right above the lobby overlooking the front driveway of the hotel - it was a small room wioth a single king bed ( we had requested 2 queen beds, as we were possibly having a 3rd adult show up) and a made-up crib in the center of the room...and I had signed a charge slip at checkin for the waterview code rate. In other words, it became apparent that OUR room was given away and they were just trying to put us in the only room left.
I went downstairs, smiled sweetly at the front desk clerk, and told him the room was - and I used this word - "UNACCEPTABLE." He didn't understand the code system at all, and he just figured he'd put us in a standardview, as our reservation said something about it. I explained the codes to him, and repeated that unless he was planning to drop our rate to the standardview code rate, there was no way we'd be staying in that room. He said that there was nothing left at the BC - so I smiled again and told him we'd happily go to any other Epcot- or monorail-served deluxe. He went into the back to discuss this with his manager...and magically came out with a 1-bedroom BCV for us.
If I had stayed in the first room all weekend, I would probably feel the way you did (and still do!!) - I had never coimplained at WDW before, and I was scared and felt "difficult." But you know what? I am a frequent visitor, and I give them a lot of business....and I am pretty nice and low-maintainence!! I will NEVER hesitate to complain if I am given a room I am unhappy with again. It sounds like you are a good customer, good tipper, etc - YOU deserve good treatment and should not hesitate to pursue it!!!!!
