We made our own way to the park — can we book a transfer for the return leg only?

This is a common arrangement for people who reach the park by public transport or in their own car and want the way back handled comfortably. What matters in the booking is which side of the complex you name as the pick-up point, because the park entrance, the resorts inside the grounds and the open-air avenue are separate places; naming the right gate in advance makes the meeting much easier once the crowd starts to leave.

Fixing the return time when you book, rather than during the day, gives you the calmer plan. If you are unsure about the hour, setting the pick-up a little later works better than waiting at the gate. The drop-off can be your hotel, the airport or another address.
