My parents took me several times and I took my son and husband , he is a history buff so he loved that aspect of the trip. We did a total planes trains and automobiles type of vacation.
Trains being my least favorite. The things we do for our kids.

We love the family membership for around 100 you can go as often as you like throughout the year , the are also nice enough to include extra tickets and the
Imax is included as well as all their special events.
The only thing lately is the prices of their food have gone up , they do have a great selection. One nice benifit is the other science centers you can visit for free, Like MOSI in tampa.
