My family & I stayed at the Grosvenor & I can honestly say that it was, by far, the worst hotel I've ever stayed at. The room was filthy and the staff was rude & unhelpful.
We had a "tower" room and ended up leaving early on a prepaid reservation.
Your $69 a night would be much better spent at the Hotel Royal Plaza on the Mousesaver's deal if it's still available. If it's not, try priceline....For $60 a night, you can get the Hilton which is much much nicer. We received the Dolphin on Priceline for $69 a night for July 23 - 26th.....
I Hope This Helps!
