Dawn,
I live in Selby so dont really have a local airport, suppose Leeds/Bradford or Robin Hood are the nearest but would both require me to drive and pay a significant parking fee. Its better for me to use public transport and Manchester is best on train but it no big deal going to London airports. I can get direct trains to kings cross(2 hours) then underground to Heathrow or to Victoria then train to Gatwick (both airports in around one hour from kings x, so 3 hour total journey).
If booking tickets in advance I can usually do heathrow for around £30-£40 return and Gatwick £40-£50 against £20 to manchester which take 1.5 hours. So its much cheaper to go to the London airports when you consider the £89 charge.
I normally book a hotel night before at either Manchester or London if a early flight or possibly on return if late back. You can get good deals and on the occasions I've gone in the car its not much more expensive to get a Hotel/Park deal as Parking only.
Last year when I did park & canyons the cheapest arking at heathrow was £75, I got hotel "Renaisance" with parking and breakfast for £90 through my AA membership.
Arranging your own flights to the resort will be expensive bcause you are likely to have to arrane your own transfers and I doubt what JY knock off cost of holiday will pay for the flight.
