Looking for something special to do with my boys next weekend

I will be induced 1 week from tomorrow if the twins don't decide to come on their own before then. But from the looks of things it looks like they are quite content to stay put for another week. DH & I want to do something special with the boys on Saturday since once the girls come we won't be getting out much for a few months. I will be 38 weeks PG with twins so something like walking around Manhattan is out. My boys are almost 4 & just turning 2 in two weeks. We go to LICM all the time so that really isn't special. Do you think the NY Hall of Science would be fun? Although I would imagine on a Saturday the place will be a nightmare. DH thinks the boys will just be happy to have a fun day out with us, it doesn't matter what we do. I tend to agree but I guess the guilt of just how much our lives are all about to change is getting to me. Any ideas are welcome, we are in western Nassau but would drive to Suffolk. TIA!

Do they like reptiles? The Long Island reptile expo is next Sunday at Suffolk community college. There's also the Bacon festival in Coram.
