The price is absolutely worth admission to TWOS if you actually take everything it includes in. It's a really great place in the city to take kids 8 and under. They are so occupied in a way that also helps them learn a lot. And their HUGE play place has a giant science water table, a mock kids plane with serving trays and light up cockpit! So cool. My daughter played in the plan alone for 30 minutes. There's also I bunch of giant building blocks, giant keyboard you walk on, a 3 and under section and much more.
There's demonstrations all the time and the staff are fun and helpful.
There's a restaurant on site. And a super fun gift shop.
If you want to visit more than twice in a year it's worth getting an annual pass.
There so much going on at TWOS that I can't even describe it all. So I'll attach some pictures.

Oh there's also a revolving rock wall. Super cool!

Just go check it out.
