We visited OMSI with four adults, a 12 year old, a 13 year old, a 9 year old and an 8 year old. Everyone found something to love about it. We all especially enjoyed touring the submarine. That was actually more popular with my crowd than the Deep Sea movie was. The tour guide was great, interested in engaging the kids as well as the adults. I recommend it.
We saw the mummy exhibit, too. Fascinating but some of us were a little 'freaked out' by it. It's very vivid and all real. It was a bit upsetting to realize that these were the actual mummified remains of real people. But for those who are interested, it was an extremely good exhibit.
Plan on spending a few hours at OMSI when you visit Portland. It was worth it.
