Welcome to planDisney, Scott! We are glad you brought your question to us.
We celebrated my daughter's 21st birthday at Walt Disney World Resort a few months ago, and she had the same concern about using her vertically-oriented driver's license. It was not a problem at all, and she was very excited to be able to present her license to purchase a celebratory beverage.
To help her celebrate, we bought a "21" embellishment from Etsy to add to her Minnie ear headband, and also picked up a complimentary "Happy Birthday" celebration button, available at
Guest Relations and in most larger merchandise locations. We had the button custom painted with her name at
Disney's Days of Christmas shop at Disney Springs. Personalization is also available at
Ye Olde Christmas Shoppe in Magic Kingdom Park. Check out the amazing floral arrangements and gift baskets available from
Disney Floral & Gifts. The wonderful team there can assemble something special for your daughter and deliver it to her Disney Resort Hotel room.
Your daughter's birthday visit will coincide with the
EPCOT International Festival of the Arts. I love sampling all the delicious bites and sips available at the
Food Studios. I think visiting the festival would be a great way to celebrate her birthday!
Scott, if you have any additional questions, please feel free to stop by planDisney again anytime. We are always happy to help.
