First - Book a room in the tower - NOT the manor. The tower rooms are newly remodeled and not all that bad. Perfect for $24 a night. The hotel actually gets 3 stars there. NOTE: They only give you conditioning shampoo - No lotion - I never pack lotion for fear it will end up all over my stuff. This is VEGAS - ZERO percent humidity so your skin will be a prune in a matter of hours. They also gave us only 2 towels for a 2-queen beds. The housekeeping staff was funny and actually caught us in the lobby as they were cleaning and handed us more towels, probably knowing we were going to call them in a few.
Where it loses stars - the lobby, the restaurants, the Adventure Dome. The lay out is weird too. It's hard to get anywhere easily in this hotel. We did have my 4 year old step-daughter with us as we were driving to Utah for a family trip and this was the half way point. She did have fun in the Adventuredome - but it's really like going to a bad country fair. Each ride for her size is $4.00 - and if she needed an adult to ride with her (bumper cars & merry-go-round) then we had to spent another $4.00 for one of us go go with her. You can buy a wrist band for the day - we only had a few hours. They are $24 for adults and $17 for kids. The hallways leading from the lobby to the rooms to the casino is filled with little stores that are full of junk.
If you're young and single - it's probably worth spending a few more bucks for a nicer hotel more in the middle of the action. If you're passing through and need a kid friendly place - then Circus Circus is perfect.
