My husband and I visited together, to see the Titanic exhibit. We also saw an Omnimax film. I can tell this is a fun place for the kids, although it was a little crowded and busy for two grownups. I guess that proves how successful it is--although it could be laid out a little better for traffic control, and I've been to science musems that had better exhibits. The air and space portion is interesting and well designed. We also enjoyed the film... Omnimax is a unique experience.
Parking was a bit expensive for my taste.
