Has anyone been to this with their family? I will likely be passing through there this month with the kids and was thinking of stopping for a day to go. My girls are 9, almost 7, and 4. It has stellar reviews online but was wondering how age appropriate it is for my youngest. The toddler area that would likely be ideal for my 4 year old doesn't look to be open yet. Would you recommend it for the younger set? Thanks in advance.
