This is a TINY space (3 rooms), but there's a lot packed into it. The exhibits are sturdy and ALL are hands on. We took our 2 y/o children, and there were only a few exhibits they could really get into (simple machines, gyro wheel, closing a circuit with your body, roller coasters, bottle rocket). BUT, those exhibits had them enthralled, and there were several that they could sort of play with, which makes me think a preschooler would love this place.
There were also several exhibits that were appropriate to older children all the way up to high school--the brain one pictured, some cool optical ones, and a room all about nano-technology.
The staff and volunteers are wonderful. They were happy to show even my little toddlers everything, and to excite their curiosity in the sweetest ways--when one was sitting on the circuit-connecting exhibit and clearly not getting it, a staff member quietly came up and played with it next to him (by not talking right away, he didn't trigger the stranger-danger in my toddler, and he made him interested to try more. It was a very age-appropriate way to handle the situation).
This was not a full day or afternoon-long experience, but it is well worth a quick side trip for bored kids in the car, it's free under 4 and they can really learn something.
Don't let the simple outside appearance, small lobby or dingy hallways fool you, the rooms here are clean, modern, and comfortable. Our room has two of the most comfortable beds I've slept on in a trip that is 1,700 miles so far. The front desk staff (a middle aged woman with short dark hair) is hands down the friendliest I've seen in a while. There isn't a pool or anything like that, but it's a great place just to rest your head. The hotel fills every night, and it seems to be a lot of people here for construction and contract work (which is nice because they're quiet at night after a long day of work). If you have to stop in Bismark and just need a nice room to sleep in, nice people, and a location just off the high way, this is the perfect place.
Words cannot describe how awesome this place is.
Stayed here with young toddlers--and loved it. The hotel room is sparse but has a fridge and microwave. It is clean and the staff is friendly. For an additional $10, we can have our pets. But the best part of the hotel is the amazing pool area. It consists of a large hot tub, a regular pool for adults and children, a small pool that is 3 feet deep that also serves as the splash down point for a big waterslide (for users 48" and taller), and a wonderful kiddie pool perfectly sized for toddlers. The kiddie pool has a turtle fountain, small waterslide, and ramps in from 0" to 1 foot deep. The whole area has a forest theme that is much cooler than I can describe. The kids and adults all had a blast. You can't get better for the price.
