As I was helping organise the swimming I can do the best I can on this. He looked at Hengrove and I was looking at another pool. The other pool didn't come off - so we're booked into Hengrove pool as far as I know. I'm not sure if he got 2-3 or 3-4pm. You can google Hengrove swimming pool and it will take you to the Parkwood Community Leisure website (sorry, on iPad and it doesn't want to play at posting a link.) The postcode is BS14 0JZ. It has a multi storey car park that is free for 3 hrs. I know that bus routes turn around there, so it's busable but you could work together for lift shares. If you want to look up buses, Bristol uses First Bus.
What else can I help with?
I'll bring the game. I've also got a few balloons I found.
