I stayed at Marriott Grand Chateau for 2 nights. Ultimately, I left with mixed feelings that I will address below.
First, this isn't a full service hotel. You won't get housekeeping on a daily basis, nor will you get turndown service. Further, there is no breakfast options for Marriott Platinum guests, which is highly disappointing.
On the flip side, the rooms are large and even have small kitchens, which is a nice feature. There's also no smoking in the hotel, which I really enjoyed.
If you keep your expectations in line, this is a great option one block from the strip.
