Hi, Penny! There really are no limits as to the number of things that might be available to you as you celebrate this magical milestone anniversary! There is everything from a behind the scenes tour for the whole family to a private dessert party to a complete vow renewal package. Whatever your budget will allow, you will find something special to help you celebrate
You might rent out the Grand 1, a luxury yacht at the Grand Floridian. Holding up to 17 guests, you can have private dining bring on a real party with food and beverages as you glide around Bay Lake and the Seven Seas Lagoon, just in time to have your own front row seat for the amazing fireworks from the Magic Kingdom. Smaller boat options are available, and you could even do a private boat for a viewing of Illuminations from EPCOT.
Disney Fairy Tale Weddings can help you plan a special ceremony to renew your vows. The Escape package, for up to 18 guests, will allow you to customize the ceremony to fit your style and personality. I highly recommend their services to give you a truly memorable experience.
You can book a private dessert party to watch Illuminations as well. Choose a location such as right by the pub in the UK or Italy Isola across from the Italy pavilion, which will give you a private space with excellent viewing of Illuminations, plus a delicious dessert buffet.
There are four star dinners, Family Magic Tours, and other fabulous things you could do. Let me know if there's something more specific you have in mind, and I'll get you there!
