Hi Andria,
A summer vacation to Walt Disney World Resort sounds really exciting.
The Resort will Awaken this summer with some awesome new experiences. So many it's very hard to list them. Animal Kingdom Theme Park will stay open during the evening with lots of excitement like
Tree of Life awakening during the night, or experience nocturnal encounters at
Kilimanjaro Safaris. At Epcot,
Soarin' Around the World will open in June, in addition to the attraction
Frozen Ever After. And Disney's Hollywood Studios brings
Star Wars: A Galactic Spectacular, which I cannot wait to experience it. Check out the
Disney Parks Blog for updated information.
Although you can most definitely make a reservation under a different promotion, you should note that this is basically a different reservation, and you need to verify that there is availability. If you are looking at splitting some of your members of your party into this new one, you would need to modify the other reservation as well. I suggest you call a vacation planning specialist at (407) 939-1936, or your travel agent, in order to make the new reservation, modify the original one, and link them together.
Hope summer comes soon enough for you so you can starting having some fun. See you real soon!
Ricardo.
