Things to do for 1yr old bday?

okay so! my little one is turning 1 on May 5th, and we’re wanting to make his day special even though he won’t remember it. we’re honestly looking for anything in the NE, but my husband and i really want to go to NY anyways. (we’re technically in eastern PA but we’ve got hotel points to burn and as someone who grew up in TX everything feels so close here lmao) any suggestions that aren’t just an indoor playground? i know i could just google zoos and aquariums, but i wanna know which ones y’all prefer etc. we don’t need anything that requires a booking for a party, it would just be the 3 of us since our family is in the south. <3 many thanks in advance.
