We visited Jump Street for our first time today with a couple of friends from playgroup. It's a great idea and the kids had a blast.
The play area for 7 & under is small especially compared to the rest of the place. There were about 25 toddlers jumping in the small area where as there was only about 5 people jumping in the rest of the place. Seems like they should cater to the majority.
Also, they were doing some kind of construction which consisted of them going through the 7 & under play area again and again with 2x4s and wood and construction supplies. It should have been done during non-operating hours, it was ridiculous.
