There are few options for childcare on the Las Vegas Strip, which is why I suggest you switch off parents or bring a second set of adults so one set can play adult games while the second does kid stuff with the children. If you want a few hours of "grown-up time" I'd suggest checking into the following:
The station casinos (Boulder Station, Palace Station, Sunset Station and Texas Station) have an on-site childcare service. Kid's Quest will sit kids aged 3 months to 12 years old. Their hours are 9am - 11pm Sunday through Thursday and 9am until 1am Friday and Saturday. The cost per child is $5.25 per hour Monday - Thursday ($1/hour off with your slot club card Monday - Thursday) and $6.25 per hour Friday through Sunday.
Kid's Quest can watch your children for a maximum of 3 1/2 hours in a 24 hour period. They offer the standard services, video games, movies, toys, activities, etc. To contact them, call the hotel 800 number (see hotel list) and ask to be connected to Kid's Quest. You must remain on the premises to use the childcare services.
The Orleans has a similar program as the Station Casinos. They will supervise children ages 3 months to 12 years old from 9am to midnight, Sunday through Thursday and 9am to 1am on Friday and Saturday. Their cost per child is $5 per hour ($4 per hour with a slot club card). Again, the maximum time a child can stay under there care is 3.5 hours in a 24 hour period. For more information, you can call the Orleans 800 number (see hotel list) or visit the Kids Tyme section of the Orleans Website.
MGM has probably the most extensive youth-service facilities. Mike (the Manager of the youth services department) sent me the following information. I thought I'd just post his information as it's very complete.
The MGM Grand Hotel has created a very special place for visiting youngsters from out of town. This special facility is 3,000 sq. ft. and divided in to four different rooms. MGM is the only "Strip" hotel that has chosen to offer it's guests an exciting program for the thousands of kids that visit each year.
Children 3-12 yrs. can enjoy a fun exciting, fully supervised facility, and participate in such activities as playing on a pool table, foos ball, air hockey, super-nintendo, nintendo 64, do arts and crafts, play dunking basketball, dodgeball, floor hockey, explore a two story playhouse, lego table, play kitchen, blocks, barbie dolls, dinosaurs, puzzles, tumbling, blocks, musical chairs, relay races, full length feature movies, and much more, all while playing with the exciting counselors and other children from all over the world. Beepers are available at a small charge, so that the Youth Center cast may reach you if anything comes up.
This is a kids dream, and over 130,000 children have found this Youth Activity Center to be one of the most exciting vacation spots ever placed in a resort destination. It even has it's own kitchen, and serves snacks and full meals snacks-$2 lunch and dinner $5. Hours vary, but usually range around 10am to midnight MGM guests children $7 per hour NON MGM guests, staying at other hotels $9 (subject to availability) On busy holidays, and summer time, all out of town guests can make evening reservations, as space is limited and it does sell out quite often.
The MGM Youth Center is the hottest child care center in the resort industry, and kids can't wait each day to come back and participate, while parents go explore their own fantasy activities.
Unlike the Kids Quest at Station Casinos, and Kids Tyme at The Orleans Hotel, the MGM Grand Youth Activity Center is on the Strip, and also has a special license for the amount of time a child can spend at its program. Other child care programs have a limit of 3 1/2 hours in a 24 hour period. The MGM Youth Center is 10 hours. You may use it for 5 hour maximum, a mandatory two hour break away from facility, then you may return for another 5 hours. For more information, please call the Youth Activity Center directly at (702) 891-3201
