When in Vegas, I actually enjoy staying at places that don't have a casino; the Marriott Grand Chateau does not, but is still within walking distance to the Strip.
We had two rooms connecting, with a huge kitchen area to share, and it was really welcoming to come back to the hotel after a long day. The beds and linens were first rate, and even though I'm not usually a fan of valet parking, the staff were very hard working and kind and efficient. Both rooms were very ample.
Great lobby, too. The pool we didn't use, but did go upstairs one night for a drink with a great view.
A great experience.
