You'll love concierge. I don't truly believe it is worth the money unless you have a big group, but if your points were going to expire then enjoy it. They have warm scones/shortbread shaped like mickey heads with jam in the afternoon. I love those. I don't think that there is anywhere else that you can get them. Also they have DVDs that you can borrow. Also if you have any children, at night they have like little slumber parties for them to watch movies and such.
If I was trying to just stay at the Grand, I would book a standard room because they are all the same size, bascially small. J/K. Some standard rooms have nice views of the couirtyard. Ask to be by an elevator, because some halllways are really long especially after a loooong day. Have fun.
