Hi, Shshauna! Here is a bit of good news. Upon arriving, the first thing you will want to do is check-in at your Walt Disney World Resort. You can do this
anytime on your arrival date. Even if it is before the check-in time, you will go there to get your Key to the World card. It serves as your room key, park tickets, and dining card, if applicable. You will need it to get into the park and to use your Disney Dining Plan, if applicable. Your room will probably not be ready if you check-in before the set time, but you can leave your bags with luggage services, and go enjoy the parks! Disney has a wonderful service that will call or text you to let you know when your room is ready.
On your check-out day, you could have one last character breakfast or lunch (at a Resort if you don't have any theme park days left), take one last dip in the pool, do some last minute souvenir shopping, or even hit one of the parks to do those family favorites one last time - if you have another day's tickets. The Bell Services will gladly store your luggage while you enjoy one last day. Whenever you are ready to check-out of the Resort, simply explain your plans to the Bell Captain, and he/she will give you a claim tag for your luggage. Be sure to allow yourself plenty of time for transportation back to the Resort and to get your items retrieved from luggage services for your return trip. Happy planning and have a magical vacation!
