Hi, Megan!
Thanks for visiting the Disney Parks Moms Panel!
The yellow luggage tags that you received in the mail should be placed on your luggage before you arrive at the airport to check-in. The yellow tag is used to identify luggage that will be transported to your Walt Disney World resort while you ride
Disney's Magical Express to the resort.
Once your vacation comes to an end and you check out of your Walt Disney World resort be sure to stop by the resort airline check-in before noon. At this point, the yellow luggage tag will not be used. The Cast Member at the resort airline check-in will place new luggage tags on your items and then have your bag sent to the airport!
So, you won't need an additional yellow luggage tag for check-out. However, if you have more than one piece of luggage that needs to be delivered to your resort room, be sure to call, 1-866-599-0951, at least 2 weeks before your departure to make sure you receive those extra tags before you leave.
Enjoy your upcoming Disney vacation! If you have more questions, please visit with us again soon!
Happy planning,
Korliss
