Premium Economy is the only way to fly....Seperate check-in is great, especially on the last day, last time we were there Downtown Disney was closed so we had to use the airport, got to the Virgin Desk and you should have seen the length of the queue, then we saw Premium economy check in - only 2 other people in line!!!!
I think last time Dollar told us we were the first people to pick up our car from the plane as your bags are unloaded first also so you get a jump start.
Ideally all the seats are fine, but if no one is behind you that's even better!!
It's good to get your own dedicated crew also. You'll love it !!
