Hi there Lisa!
I am so excited that your child is getting such a magical experience. I traveled to Walt Disney World with my show choir in high school, and those memories are some that I will cherish forever.
What you can add to your package will actually depend on what type of package the marching band booked for your group. I would try and reach out to the travel coordinator to see if they can give you any additional details. Sometimes they have included a dining card, but not always.
The one thing that I know you can add is Memory Maker and a
MagicBand. The MagicBand will make for a great piece of memorabilia, and the
Memory Maker will ensure that these moments last a lifetime.
I also recommend that you stock up on
Disney Gift Cards prior to the trip. Not only will this help your kid stick to a budget, but it will help ensure that no credit cards get lost on the trip.
I hope that this helps, Lisa!
Have a magical time!
Sarah B.
