We want to go for 10 -14 days in school hols next Summer. 2 adults and 2 teenage ds's.
Booking flights separately seems to be ££££, but we want to do Universal as well as disney so I'm really not sure how to go about it. We wanted to stay at disney hotels to get the fast pass tickets. We just need to get it booked!
Fastpass tickets are available to all who visit WDW; these tickets are timed and are issued daily at some (but not all) rides till these run out. If you stay at a Disney hotel the parks can be entered earlier.
Seeing as your children also are teenage, they may well prefer Universal over Disney overall. Also as your children are both over 10 they will both pay adult admission prices for all the theme parks.
Afraid that what you've been quoted sounds about right, children over the age of 12 pay adult fares.
Flights to Orlando are pricey anyway because the airlines know that this is a family route and thus very profitable for them. I would price comparison BA against Virgin and see what the difference is, VA can sometimes be dearer.
