We are new members and will be taking my parents along on our first trip this fall. I've not stayed in the same room as them since Magical Express started, and was wondering about how it will work with multiple flights. Will ME send the luggage tags to two addresses? Do I have to have both sets of flight info before I call, or will two calls be OK? Will the resort check-in go smoothly with multiple flights/airlines? I'm sure Disney deals with this sort of thing all the time, but was curious about how well it works. Thanks!
