My son is 19 month old and I clarify this to be fair with the business
The place should not be targeted to toddlers! They do have a chalk board and some letter tiles but those are not worth $9 admission. It would be ok if I come with a 6 yr old and a toddler and the toddler gets free entry but to come in with a toddler only is certainly not worth the time or money.
Also - even for older kids - I saw a few enjoy the climbing wall and the castle and the slide BUT they were there only for maybe 30 min and then some went to play at the arcade type area. If the arcade section is included in the price then I'd say it's worth it but If those are charged per use then NO.
Recommendation for the business: reconsider including walking toddlers in the free entry
