We stayed at the Grosvenor last May for 11 nights. We got the first 10 nights at 35$/night with priceline and were very happy with that!!! The small refrigerator is big enough for milk, juice, fruits, etc... The room was OK, small a bit, but fine if you don't spend all your day inside! We decided to stay another day at disney and asked for a tower room... Much much more better! You can see the fireworks from downtown disney, rooms are a lot bigger and the bathroom is almost 2 times bigger.
Although, my husband still think that the courtyard room was a better deal (he REALLY liked the balcony, having his coffee outside in the morning, reading the paper, and paying 35$ a night...!!) Their regular rates aren't that bad to.
We are going back to wdw again this year. If we don't go for ASMo, we will definitly go back to Grosvenor!
