I was at soft play a few weeks ago for a party for DD1. I decided to take DD2 in the ball pit on my lap. I sunk so deep that I could not get up.
15 whole minutes I had to sit there looking nonchalant before someone I knew got with 'cooooeee' range.
My friend was in tears laughing at me, took DD2 and I had to do the most unladylike scramble to get out.
That pretty much sealed my hatred of all things soft play.
