For a quick trip to Boulder (for zip lining) we stayed at Hoover Dam Lodge. There were 2 adults and a teenager. Not horrible, but definitely showing age in the rooms/bathrooms. The room was clean and smoke free (un-like everywhere else, restaurant included). The 2 full size beds had clean, bug free sheets. They were a little stiff but again not horrible. However, they had the crinkly plastic waterproof covers in the mattress with a flat (not fitted) sheet over it. It was noisy and when moving at night, we found the flat sheet not staying in place so we ended up in the plastic. They offer complimentary snack size chocolates and crackers in room. Towels were thick but a bit scratchy like they'd been washed in straight up lake water. Pool was closed (only available in summer months). Gift shop/Store had everything you could need. Restaurant was awful, but that's another review.
All in all not bad for under $100 a night for a quick trip. However I'd look at other options next trip.
