yeah, only, the 4 year old, take your 10 year old, to Hansen Planetarium, which is close to ther, more up hs age and alley, even be fun for the 4 year old
My 10 year old and 11 month old liked it when we went. They have little baby areas. The best part (the water play) was closed though when we went. So you may want to call and see if they've got it open yet. I even like going. Especially upstairs where they have derby racing cars, blocks, computers, and an activity room with basket ball hoops (the size you see in arcade games), my 10 year old had plenty to do.
I took my daughter here for the first time when she was 13 months old. She wasn't super interested, but we did find a few things she was interested in. Your kids will likely be able to find something each of them woild would like, but it is geared towards younger kids.
