I have not read the other replies but wanted to share my feelings.
We went for the very first time in June 2006 and stayed at CBR. At the time we thought it was going to be our once in a lifetime trip.
Our first day was a little disappointing. We arrived to down pours. When we went to check in we were told our room was not ready so they gave us the building # and phone # to call to check back. We checked out the resort and went to the building where we were told we would be in. After several attempts and hours of waiting we finally were told our room was ready. We had been standing outside our room the whole time and never was a mouskeeper in it.

We then get in our room and I was disappointed with it, thinking we paid all this money for this?

We had to deal with the heat, humidity, lots of rain, crowds and the Brazilian student tour groups.

But after all that, the day we were leaving, I was really sad. Although we had to deal with some disappointments, we (at least I did) experienced something I never had before. The magic that I felt was awesome. By the end of our stay I loved our room and what we paid for it was worth it. We were able to MK's rope drop and the opening show was simply amazing. During our end of the trip, I told DH that if we were to ever return, we would need to pull the kids out of school and go during a less busy time.
Well then winter of 2008 rolls around and I get thinking about Disney. I talked my DH into going again. We talked it over with the girls and decided that Sept. would be the best time to take them out of school. So I started making plans. In the meantime I found the DIS and learned about FD.

This time our trip was wonderful! Although it was still hot the crowds were so much better and we only had one afternoon of rain.

My Dh said to me maybe in 3 yrs. we come back for Christmas.
Well I happened to receive an email in January about the deals Disney was doing for the military. So I mentioned it to DH and we are going THIS December. I dont have to wait 3 yrs.
My DBro and his family had gone several times and I could never understand how that could pay so much for a trip and what the big deal about it was. I now understand.

I ahve been converted and am now a WDW fan!

So what I am trying to say is don't go with high expectations and you will not be disappointed.

The magic that you will feel is indescribable. Go and have a fabulous trip!
