Haven't been to many despite I love to swim. If I was living near decent swimming pool area (my local one sucks) I'd probably glad to visit it often. That being said, Blackpool one is amazing. Despite expensive, (about £10 including rides...and that's with my disability ) it was worth every penny.
I didn't realise it was a bump at first. Saw the pic Smurphy posted on page one and thought "That looks like the Time Capsule". Get to the next page and there's a post from me saying "That looks like the Time Capsule".
I've not actually been swimming in about 20 years though. Just not something I think to do anymore.
