I took two 5 year olds and a 3 year old on a weekday morning just as they opened. Even with a few yellow buses of field trippers there, we had plenty of room to roam. The museum has SO much to see and do. Upstairs, downstairs, inside and out. If you try to see/do it all in one day you will be overwhelmed! Take your time to enjoy what your kids can, and plan a subsequent visit to do more. It will give them something to look forward to!
Our favorite exhibit is Kidtropolis, a mini town with plenty of hands on opportunities: bank, TV station, HEB grocery store, vet clinic, restaurant, ambulance, government hall/city planning and voting booth, etc. It is really impressive! The admission fee would have been adequate for my girls just to enjoy this.
There are plenty of science type activities, crafts, African village, waterworks fun outside, cars to sit in, pretend play, animal nature house, climbing maze structure called Power Tower, gadgets to try out and build. The list goes on! Plus, a large seperate area for toddlers and younger only.
I would recommend tennis shoes for kids. There are a couple of popular activities (like rock climbing, Power Tower) that you arent allowed to do with anything but them (not even crocs).
The museum is very accessible. There are lockers in a coat room near the entrance that you can use for 25 cents (and you get the quarter back!). Bathrooms are easy to find, and the cafe is good with some healthy options, too. Grilled Chicken Breast Sandwich $5.95, corn dog $2.95, fruit salad cup $3.95, juice box 95 cents. There is a covered parking garage adjacent to the museum, and you pay per hour with a maximum of $8 (3 hrs or more). The gift shop has a great selection of toys, some unique and favorite brands and lots of educational stuff.
The museum staff are all so kid friendly and helpful. Admission is $8-9 person, and check out the website for discounts available. Bank of America customers with a valid card to show get a discount one weekend month, Thursdays 5-8 are free, etc. There are yearly passes available, and if you live nearby that's the way to go.
It really is an amazing experience for kids, and worth the drive if you don't live in the area. We spent 5 hours including a lunch break, and the kids had a very full and fun day (and slept well that night!)
