Hey there, Heather!
Thanks so much for stopping by today with such a great question.
I am thrilled to hear the you are entering EPCOT at the International Gateway. By entering at the back of the park, you will be able to avoid the "rat race" to get to the all-new
Remy's Ratatouille Adventure! I was lucky enough to get a squeak-peek, and I have to say, it was such a fun ride for the whole family.
Heather, generally at least one ticket booth stays open until the theme parks close for this exact reason! I have heard from a furry friend that occasionally the ticket booths at the EPCOT International Gateway closes two-hours before the
parks close. If that is the case, then you can head over to
Guest Relations, which is located right outside security at the International Gateway, and they should be able to help you out.
Have a rat-a-ful day!
Sarah B.
