We were there on a Thursday afternoon, and parking wasn't an issue - I found a space easily right outside. I can imagine though that when it's busy that it could be an issue as it's on-street parking rather than a car park. I paid just under £10 for entry for the kids, which I think is ok given all the activities inside.
I literally couldn't believe the size of the place when we walked in - it's gigantic (just checked their website, and it's apparently the biggest soft play in Glasgow). The ceilings are so high and the space is immense. This is the type of venue that would panic me if it was busy - I'd be terrified of losing them (I know it's got a locked exit, but you just never know!).
Thankfully it was quiet and my friends and I picked a table that gave us quite a good view of the area.
There's one other drop slide which was an even steeper gradient, but thankfully it was shut!
I didn't have any food at the soft play, but spotted a family with a pizza, chips and nachos and it looked & smelt decent. You can have a look at the menu here. They also serve Starbucks coffee.
I really don't think I'd like to come here if it was busy and would make a point of avoiding it at the weekend. We timed our visit quite well and the children that were in the soft play were all of a similar age, but I can imagine it would be rougher if there were older ones about.
One negative point was the music. I heard the song Icona Pop, I Love It at least twice whilst I was there and it wasn't a radio edit. With lyrics including 'You're from the seventies, but I'm a nineties bitch' and 'I threw your shit into a bag and pushed it down the stairs', I just don't think it was appropriate for the age of the children that were there.
Have you been to Wonder World before, what were your thoughts?
