I think 4 stars is being a little generous - but at the same time, it wasn’t bad. Pros: the area about physics with the movable tracks and balls was a great idea! The other children’s museums I have been to either have immovable tracks or only tracks specific to trains. (This area was very busy and had other pieces that had no explanation as to why they were there) there was a cool crawlspace and setup for the little slide and climb area in this same section, reminded me of when I was a kid and they did that kind of thing. There are a lot of vehicles set up with multiple buttons and steering wheels so the kids aren’t all fighting to get into ONE spot to “drive” the thing, with opportunity to climb around. The section with the boat and magnets on the first floor, the boat with food pulley (first floor), and third floor were the parts we spent the most time in. Good intentions on the 4th floor, getting kids moving and learning about food and exercise and sleep... and realistic driving on that wall vehicle. Also, the smell section on the 1st floor was cool. Cons: I hate to say it, but there were just not many things for kids to manipulate and get their hands on. There weren’t enough balls or magnet pieces for the very popular areas, there was NO FOOD to play with or pretend to pick up and grind in areas about food (see pic of showing kids diff foods from the Middle East - covered in plastic so the kids can’t touch). The second floor was dedicated entirely to Dora and Diego - I appreciate the effort on spanish and English words and integration, but, again there was like nothing to DO, he could climb on section and look through a telescope. Walk over a bridge, and just look at things. I don’t know if things were missing but, if it was it was A LOT of things missing. Third floor was decently good, this was def their best floor, but no gate or anything for the baby section which is unusual. The fourth floor was sad. The health room looked like effort was slightly made, but.. eh. The vehicle on the wall was the highlight - flip flaps for body stuff was interesting for kids who can read. There is a whole room for getting kids moving but the bikes don’t work well (I appreciate the effort), there is a weird thing to use as a pulley on this random set up you can climb stairs for... but it is not set up well and there were literally two balls to use with it. Just seemed very empty and thrown together. Other points: there is no map, but descriptions of the floors inside the elevators. Coat check was good. Doorman was nice. Gift shop is geared towards girls and younger children (younger than my 4 yr old boy). I want to be fair in my review, especially since I thought this was the same museum I went to as a kid (it was not) that had huge rooms set up for activities (grossology, green screens, claimable body parts that was actually like a body, manipulatives, a dr Seuss section...? Idk where that is, I thought this was it - I don’t live in NYC) so it was a disappointment at first for me - but my kid did have a really good time. We were there for over two hours. I just wish there was MORE to play with so the kids weren’t all trying to get the same three moveable things. Balls, magnets, or pouches for the pulley on the boat. (& I suppose, the track pieces).
