We will be flying into Orlando and our flight arrives at 8:30 AM local time. We will only be there 4 days including our arrival day. We plan on going straight to the parks when we arrive. I have signed up for Magical Express. We want to obviously maximize each and every hour we're at WDW. Could we take an uber or cab straight to a park to save an hour or two (we're staying at Pop) or if you're doing ME, do you have to take the ME bus to your respective resort?
