Hey, you can get flights to Orlando for £248 return from Heathrow or Gatwick. Once you're over there, accom is dirt cheap, find a motel somewhere and you're sorted. Ater that, the choice of parks is wide open. I'm off there next week for 2 weeks, so if you want any info from over there, drop us a PM and I'll let you know. Might cost you a bit more than you planned, but it's the best of the best!
The site below is where I booked my flights, so check it out. The code for Orlando airport is MCO
See how you get on.
