We are off to Orlando in May and the pound has really knocked the shine off!
We've been hunting about for the best deals on Disney passes so I thought I might aswell post the conclusion here.
Virgin holidays appear to be the best deal out there as long as you are happy to get ticket vouchers rather than actual tickets (we've done this in the past and all it means is a short delay on day 1 of your trip).
We've gone for the 7 day premium ticket which includes park hopping (multiple parks in one day) and 7 day access to the Disney water parks etc. This basically gives you 7 days of access to the 4 major parks over a 14 day period (starting the first day you use it).
Prices £183/Adult, £160/Child, this was about £30 cheaper than the other deals we found (although these are ticket not voucher deals) at places like http://www.americanattractions.co.uk/
Virgin also are very competitive on the Universal tickets (we've gone for the SeaWorld/Aquatica 14 day pass at £55/£50 which again is £10 cheaper than the rest, but the Orlando Flexticket (covering Islands of Adventure, Universal and Wet and Wild in addition to Seaworld and Aquatica) comes in at £140/£120 which is around £20 cheaper.
Hope this is useful to others who are going and are currently bogged down in web trawling and comparing all of the numerous options there are.
Note: Virgin Holidays show as offering 4% on quidco, which I did use, but so far it hasn't tracked so no guarantee.... UPDATE: Validated today so I can confirm the deal just gets better!
Note2: When going through the checkout don't worry about the "Select Your Room" page which comes up with "Internet Excursions" on it, just put the number of passengers in the box (it is basically a £1/person booking fee).
