Hola Yasily!
Felicitaciones on your daughter's Quinceañera! What a prefect place to celebrate! She will truly feel like a princess, especially since this will also be her first trip to the Walt Disney World resort. Wow, double the excitement!
I can recommend some places in order to get you started with your planning depending on the "level" of celebration you would like to have.
Disney Group Getaways can assist you in planning a large celebration if your party needs to book a group of 10 rooms or more! If you want multiple events for a large group of people as a vacation, then start here.
You can check out
Disney Catered Events if you are looking to book just the party. They will help you plan a magical gran fiesta!
If you want a more intimate gathering or want to add personal touches, then you can
customize your special occasion with
Disney Floral & Gifts. They can help you plan enchanting experiences or memorable gifts to make your daughter's Quinceañera unforgettable!
Buena suerte with your planning, and if I can help you with anything else, please don't hesitate to ask.
Wishing you pixie-dusted dreams,
Tania
