We took a 5 year old to Please Touch with high expectations, having had a great visit about 3 years ago. The building remains beautiful and is well maintained; likewise the carousel. Staff were, without exception, friendly and helpful. Downstairs was the best area for a 5 year old.
This trip the charge was $70 for 3 adults and one child plus 2 carousel tix. First stop: the Rainbow Rhythm space - disappointing, as it has not been well maintained. The step-on piano keys are out of tune and other items were incomplete, dirty or malfunctioning. The adjacent water area had handy waterproof smocks, but not much to do for her age.
Next the carousel, after a stop in the very clean and tidy rest room. Great fun, although a short ride (4 minutes for $3) but the adults could all ride with the one child, so we took advantage of that. Beautifully restored and maintained. There are attractive photo op stations here, too - stick your head into an existing picture. I think there may be a cafeteria h=nearby as there are tables and chair here. No idea what their policy is on outside food.
Next we went downstairs - this is fun-central for little ones, having separate areas for toddlers, as well as nifty playrooms for more independent ages - we visited the grocery store, hospital, and a transportation area with climb-in car, truck, SEPTA bus & trolley. Our little girl loved the shoe store. (We avoided the attractive dress-up options, because in any crowded public place we're careful to minimize risk of lice or bedbugs).
The storytime room was interactive and well done. The Alice in Wonderland maze and funhouse mirrors were a bit too old for her. Back up to the first floor to the space station activity room. Lots to do there, although again some stations were out of use. No problem on a Monday, but I'm glad we weren't there on a weekend.
Our little one had a good time. We arrived a little after 1PM and the museum closed at 4. So, bottom line: on the pricey side for 3 hours, even though we found street parking. Lots to do, but checking the website and planning age-appropriate stops in advance is definitely the way to get the most out of the trip.
