Depending upon exchange rate & your dates virgin can work out cheaper, e.g our trip next year starts 21 Aug which is still high season & rooms start at $99 (excl. tax)/night, however we got the room through Virgin for £54/night. If the dollar continues to strengthen against the pound, Virgin will definitely work out cheaper, otherwise there will be little if anything between it, but we were able to book back in April rther than wait until now when the rates have just been released. However I recently booked a trip for friends & the UK Disney site came out cheapest (visit starts 24th June) & when we went in December, the best rate was the US site where I got a discount, so there is no correct answer, just lots of fun looking, comparing & predicting the direction of the dollar!
