In the past we have bought our tickets from ticketmania.com they deliver them to your hotel & you can get some good deals. I always start shopping around about 12 months before I go, I check regularly on Disney website, ticketmania, onlineflorida.com & iloveorlando.com. I must admit it can be expensive going to all the parks, last year we spent £1,666 on park tickets for 4 adults, me & OH didn't go to Busch Gardens, we all went to KSC, but I can't remember the cost of that, I did register for emails & bought those tickets on special offer, I seem to remember it was about £40 each which included a special tour. Feel free to pm me if you want to pick my brains
