we have been 3 times to Disney and went to New York this year and all times used a company called attractionticketsdirect.com, they re prices are the best I found online, and believe me when I say I look a lot online for the best deal, they also have a price match so that if you buy them and se them elsewhere cheaper they will refund you the difference.we ahve bought 14 day disney tickets, universal pass, discovery cove, from them, this year we even purchased our New York tickets from them and found no problem at all with them. what we found was some places online send you vouchers that you need to redeem at a booth when there, but this company sends you the actual tickets that you will use there.Good luck finding the best deal and enjoy your holiday there.
You could google UK disney tickets or ask around. You never know who has connections to someone who works at Disney and could get you a good price.
