Hi, Kathryn!
You can ship a package to yourself to arrive at your Disney Resort hotel. You'll want to address your package like this:
Disney's Port Orleans Resort - Riverside
Hold for Guest: "Your name here"
Check-In Date:
1251 Riverside Drive
Lake Buena Vista, FL 32830
I spoke with a Cast Member from Disney's Port Orleans Resort - Riverside and they unfortunately are unable to open the package. I do have a suggestion as far as surprising your daughter with the costume. Maybe she'll want to go check out the pool area after you check in and you could all wander out there. Someone could [say they need to run to the restroom] go back over to the front desk, get the box, quickly go to your room and lay out the costume, and go back out to meet up with the rest of the party? Sometimes us moms can get away with pulling a fast one like this depending on the child's age!
There are a couple of fantastic Character dinners in two of the Resort hotels.
Chef Mickey's at Disney's Contemporary Resort is a VERY popular one and it's awesome! You can meet Characters such as Mickey Mouse, Minnie Mouse, Pluto, Donald Duck and Goofy.
One of my favorites is Cinderella's Happily Ever After Dinner at
1900 Park Fare inside Disney's Grand Floridian Resort & Spa. Here, you'll be the honored Guest of Cinderella and Prince Charming. You may also meet her two Step-Sisters, Drizella and Anastasia, as well as the Evil Stepmother! It's really a hoot!
Reservations are highly recommended at both locations and can be made either online or by calling 407.WDW.DINE [939.3463]. I hope this helps! Please let us know if we can assist with any other questions and have a Pixie Dusted vacation!
