Hi Claire,
Thank you so much for visiting the Disney Parks Moms Panel with your question!
Bay Lake Tower at Disney's Contemporary Resort is such a great resort. My daughter requested to stay there for one of her birthdays, too! We love the sleek, modern theme of the resort, and the ability to walk to Magic Kingdom is fabulous.
I spoke with a wonderful cast member at Disney Vacation Club Member Services today about your question. He suggested that if you want to have guests come to your room who are not on your reservation, you should have those non-registered guests noted as day guests. If you are a Disney Vacation Club member, you can call Member Services at 1-800-800-9800 to discuss this with a cast member. If you are not a Disney Vacation Club member or if you prefer, you can call Bay Lake Tower at Disney's Contemporary Resort at 407-824-1000.
To add some extra magic to your celebration, consider working with
Disney Floral and Gifts. They can work to customize a gift just for your little one. My daughter loved the plush Minnie Mouse and balloons that we had delivered to our villa for her 7th birthday. You can call them at 407-939-GIFT (407-939-4438) to customize a gift for your daughter.
I hope that this information is helpful for you, Claire. Have a wonderful time planning your magical vacation, and please do let us know if you have any further questions!
