We have just booked (today!) to go to Florida again this summer. We ae off for a fortnight on the 30th July. t will be very hot, but it is school holidays and we know what to expect as have been 3 times before int he summer. It is hot but bearable.
We are going with my parents, so 5 of us, and we are getting a villa, like when we have been with them before. When it was just the three of us we stayed at Animal kingdom hotel - but much dearer option if you need more than one room.
Again this year (and in 2009) it has been cheaper to do it as a package through Thompson. By a couple of thousand pounds too! the first two times we went (2004 and 2006) doing it seperately with Virgin flights were the best optins. however this year at least flights are very expensive in school holidays. We have just booked for 4 adults and 1 child for 2 weeks in August, with villa and flights for £4500. We will have car hire on top and tickets.
Easter is a bit cooler but much busier. It is as busy as Christmas over easter weekend.
My dad has just sourced a ticket for £400 each which covers all the parks in the area plus water parks, and Sea world, space centre, and Busch Gardens. We do parks every day - even at 2yo DD never waivered and just wanted more and more! - so this works out as the best deal for us so far.
The queues at DisneyWorld are much shorter than Disneyland Paris - so you will notice a big change there.
