I have stayed there twice. The first time was in 1998 when it was still pretty new.
I stayed there again in 2012.
In '98, I loved it. It was beautiful and clean. I was in my late teens at the time, and loved the pool and the lay out of the resort.
Before staying there in 2012, my mom and I went there for a few meals during trips where we stayed at other properties. They were nice visits: good food, nice atmosphere, clean, etc.
2012 was the opposite. The room was clean, but the rest of the resort was filthy. There was garbage in the stairwells that sat there for days! Even after we told several cast members about it. And then there were the rats. Oh my god, the rats. By the lobby, by the small pool near our room, in the stairwell mentioned above munching on some melted ice cream and other garbage tucked into the corner. One ran across my foot while I was sitting on a bench outside. Another ran in front of my mom when she walked to go get a cup of coffee. We went to the front desk, told them about the rats and all of the garbage and were basically told there was nothing they could do about it. We asked for nothing more than getting the garbage cleaned up in hopes that maybe it would help the infestation a little. Finally (halfway through our stay) my mom found a cast member walking near our room, asked him to follow her, showed him the garbage and he got someone to clean it.
I don't know. A lot of people seem to love it. But every time I think about CSR, I picture the rat in the stairwell eating days old melted ice cream and think nope. Nope nope nope.
So, yes. To me it is as bad as the reviews claim it to be.
