We stayed here for a week during CES, and we had a great experience. The rooms were clean and were well kept. The cleaning staff was very nice.
Like:
Dinner buffet - fresh oysters, king crab, salad bar
Indoor waterfall
Plenty of parking - outdoor parking as well (excellent security--there is a security staff checking the parking lot throughout the day)
Competitively priced rooms
Would highly recommend Sam's Town Hotel & Gambling hall for your Vegas stay.
