I just won't go to a theme park during school holidays. I've been to Florida twice, both times in September and the American and British kids were at school and there were next to no queues at any rides. It was pretty awesome. And the roller coasters were world class. The Hulk is one of my favourites. But the best park for roller coasters is Busch Gardens. Sheikra was my favourite coaster. There's an old style wooden one there too. They jolt you about something chronic and aren't usually very fast/high/intense. Also being a tall chap the restraints can be tight. My shoulders get most of the punishment on newer coasters and my knees on older lap bar style ones. Although generally amazing rides and the day we were there zero queues. If I was there during busier periods I always said I'd pay extra for fast passes.
We all know the UK parks just don't compare but Alton Towers seemed to be trying to make a decent fist of it. I think there are a few new rides since the last time I was there. Smiler being the newest one.
I've never bungeed or jumped out a plane. I think I'd like to. But I dare say it's a hell of a lot more scary than even the most intense theme park attraction.
