Are you doing Universal and Sea World too? If so my brother said ride the Kracken. I haven't been to Florida but he said absolutely no downsides except his ankles swelled up after the flight because of the heat etc. Enjoy!
No, it's not school holidays but we have been granted authorised absence (because of himself's on going head problems). We are doing Disney/universal but himself is not going to go on any 'shaky' rides.
Hope you all have a brilliant time - we were there in April. Have you had a look at the new fast pass system? You can prebook things online, which actually makes it harder to get a fastpass when you are in the park. Hope you have planned most of the things you want to go on, you need a plan of action! Although the queues should be smaller than they were in April, it is still useful to plan in advance.
We have booked some fast passes already and have a vague plan. We only booked it four weeks ago so haven't had that long to get organised, but I'm sure it'll be fine :)
