We do not plan on hiring a car. Unless DH really wants to for a trip to the space centre.
So land and taxi to Cabana Hotel for two nights to get express passes in Universal. Do Harry Potter.
Move to Saratoga Springs in a one bedroom suite for 12 nights or may be 14 and do parks including water parks for rest days and shopping etc.
Thinking that doing Universal first with express pass will help. Quicker queues and no long waiting if we have jet lag. Then we are fresh and ready for Disney.
This is currently for 2018 so getting DDP included.
