Friend and I decided to take 5 DC's to an inflatable swimming session at leisure centre yesterday.
They have a large walk along inflatable and then a few surf board type floats. There aren't really any alternatives to the inflatable and during public sessions in the holidays they get the floats out anyway.
There is no information available on brochure or website about session restrictions etc. We rang up and said we had 5 DC's, 6,6,7,12 and 13 yo. We asked if the session was suitable for them and if they could use the large inflatable. We were told they had to be strong swimmers (swim 25m length) and under 8's must be accompanied by an adult in the pool. All but a 6yo is so we decided to go as she doesn't like deep end so wouldn't have wanted to use it anyway. It is more expensive than a normal swim.
So we get there and order the tickets, to be told the 12yo is too tall to use the inflatable. Admittedly she is 5"7 but they hadn't said there was a height limit on the phone. The 13yo is about 2cm over but he's OK as he's only just over.
Apparently it's for insurance purposes but a little doesn't matter. 
A group of girls were behind us who were just coming as a group as one of thems birthday and an 11yo in the group was 3cm over and after much persuasion of the parent she was allowed in and on the inflatable.
We spoke to centre manager and were allowed the 12yo free of charge but not to use the inflatable.
Basically this used to be the most popular session at the pool, people queuing outside the door from 1/2 hour before session to get in. Now it's very quiet.
To use the inflatable you must be able to swim a length well (so on average probably age 8 up and under 150cm so on average under 12 yo.
AIBU to think they need to find a swimming session that is more inclusive, and useful for families!, or at least have this information available so people don't turn up and be disappointed?
I am hoping to get some good suggestions from MNers so I can suggest them for our centre.
