Ah, yes, good ol' EWR. Hopefully, the queue for Immigration won't be terribly long when you arrive, as it does tend to move much more slowly than in Orlando. (If this does cause you to miss your flight, though, there are generally plenty of flights available to MCO to be rebooked to.) Since I work for the other big British carrier that hasn't been mentioned here, I have spent plenty of time assisting passengers in the arrivals area of Terminal B. If you arrive at this terminal, as plenty of Continental international arrivals do go there, you will have to hustle, since you will also need to take the AirTrain monorail to Terminal C and clear security there. However, if you arrive in Terminal C, you should have an easier time as you will only need to clear security after finishing with border control.
