Hi Brooklyn,
Congratulations on your upcoming celebration!
The Villas at Disney's Grand Floridian Resort and Spa will be a magical place to spend your honeymoon.
For your dates, you should be able to book at The Villas at Disney's Grand Floridian Resort and Spa now, if you want to book at this resort using a traditional payment method such as a credit card or cash. I called and spoke with a cast member who told me that she was currently able to book at this resort into September 2014. I suggest that you call Disney at 407-W-DISNEY (407-934-7639) and work with a cast member to see if your dates are available.
If you are a Disney Vacation Club member, if this is your home resort, you could book now as you are within the eleven month booking window. I would book by calling Disney Vacation Club Members Services at 1-800-800-9800. If this is not your home resort, you would need to wait until seven months before your trip. By calling in any case, you will be able to work with a cast member to determine availability.
My guess is that you might be having trouble finding availability at this resort as it is a new and beautiful resort, and lots of people are probably trying to book reservations here. If you cannot find availability at the villas, I suggest trying to book a room at Disney's Grand Floridian Resort and Spa - the hotel side of the resort. I spent a weekend celebrating my graduation with my husband there, and it was wonderful.
I hope that this information helps, Brooklyn! Have a wonderful time planning your honeymoon, and please feel free to come back and visit us if you have any further questions.
