Yeah I expect the flights have some bearing but it shouldn't be £3k more with the same flights selected and hotel etc.
At present 16nights 17 Oct
@pop with Disney Tickets, car hire Fully Inclusive Insurance, Economy Out we are 1 stop coming back (as that's all I could get at the time for my current booking so I have matched that here, Premium seats Inbound both flights) £10,360 with discount = £9700 ish.
Our Booking is same nights and date, at Coronado Springs, same car hire, same flights and it was £6700
Thats crazy difference in price no doubt I can get it cheaper from someone else but would then lose deposit probably.
So for me im hoping I go in October as even with the dining it would most definitely be more expensive.
For Next May it would be £11,091 or £10,314 so the offer is worth say £800 dining and gift. still makes it £9,513.
