Where to go on holidays to usa?

Hi, i am thinking about going to the usa this year, i love the usa i think it is perfect and i'm trying to persuade my parents to go there as i can't stick europe and couldn't bear another year there again! But the problem is my parents don't want to travel the whole way to florida as they said they hated the long flight the last time, so i am trying to find somewhere close to the uk that is really hot around 35c and is like southern florida but is cheapish? Where the heck would that be? I don't think there is anywhere in northern usa like that is there? They said they'll be fine flying to the north of the usa about a 6 hour flight but not southern usa or anywhere else as its cheaper and the flights are alot longer! The place would have to have alot of restaurants i.e outback, pizza hut etc good cinemas loads of shopping malls and really good theme parks like disney world etc.. and it MUST be hot not somewhere like maine where it will be 20c or something... Thanks.. It has to be a closish flight as well so that the flight can be cheap as the flights to florida are �2000 and if we went closer it would be cheaper. Please don't be recommending washington or new york as i want a hot place not a city with lots of beaches and a tropical type place... i think thats going to be very hard to find.
