I don't blame OverbookedDave for any of the things that happened at all. It is entirely reasonable to use the services of a travel agent for a Disney trip, especially if you are short on time, and you are encountering waits when trying to book directly. I am very glad that Dave got the Boardwalk reservation he originally wanted. He has not mentioned whether he had worked with this travel agent before. I don't need to repeat what others have said about what the travel agent should have done.
I have almost never used a travel agent since I used one in 1973 to arrange for a flight to Austria and back. The agent booked me on a flight to Paris, with a different flight number to Vienna. However, she told me that it would be the same plane. I doubted that somewhat, but went along with it. Overnight, on the plane, I lost one of my contact lenses. I arrived in Paris, and waited in my seat for the new travelers to board. No one came on. Eventually, the stewardess asked if she could help me. I explained. By that time, the flight that had been reserved for me had already left for Vienna. So now I needed help rearranging that flight, I was able to see out of one eye only, and I did not speak nor understand French. Fun! This did not go badly, however. I was able to get a flight to Vienna with a stop-over and change in Zurich. This was quite nice. It was the first time I had seen real mountains. When I arrived in Vienna, my luggage was there. The flight back from Vienna was one of the best flights I have ever had. I was on a 747 from Vienna to New York. There were very few other passengers on board. I had an entire row of seats (in coach) in a 747 all to myself! The stewardesses were ecstatic! We had wonderful service and a very smooth flight. This was on TWA.
