Hola Romar!
Welcome to planDisney! I am so excited to be helping you prepare for your daughter's quinceañera! I'm sure your daughter will love it and I have some ideas that can help you.
Your best option for something spectacular is to speak to the Cast Members at
Disney Meetings & Events who will be glad to make magic happen for you and your family! Just let them know what your vision is and I am positive they can find a way to put something amazing together for you. They can even help you secure a photographer and plan other special surprises!
If you want to have instead a small dinner for immediate family you could just plan one yourself by booking a
reservation at a table-service restaurant. Now, this can get difficult if your party size gets too large as I find booking parties of 6 or more a challenge. It's possible but your options are limited. Consider restaurants at Disney Springs or the Resorts for a better chance of getting a reservation for a larger group. I suggest
Boma-Flavors of Africa at Disney's Animal Kingdom Lodge or
Paradiso 37, Taste of the Americas at Disney Springs! I would also try
speaking to a friendly Cast Member who can try and assist you in securing reservations.
Walt Disney World Resort has a wonderful experience called
Capture Your Moment that is available to be reserved for any of the four major Parks. You pick your park and your date and time and just show up ready to shine! You will get a 20-minute session with a Disney PhotoPass photographer in the Parks. They will capture your daughter's best angles and moments! Just for fun, I would consider a daytime and then an evening session so you can capture her in different lighting. I can only imagine how beautiful she would look in EPCOT in the evening.
As an additional special surprise, if you are staying at a
Walt Disney World Resort Hotel I would consider having a lovely
flower and gift arrangement sent to the room. It would make any young woman feel special and loved.
I hope this helps and I wish your daughter the happiest of birthdays!
Let me know if you have any more questions!
