Hi, Renee! Because Shades of Green is not a Walt Disney World owned resort hotel, you cannot make your dining reservations longer than 180 days in advance. That means that you will have to call 180 days in advance of each day of your stay to make a dining reservation for that day.
Hotels not owned by Walt Disney World do not qualify for the "plus 10" perk. Guests staying at a Walt Disney World hotel can call at the 180 day mark and make reservations for up to 10 days of their vacation.
I'm sorry that you have to wait each day to make your reservations! It's a bit easier to do online, however. You just have to head to
Disney World Dining and browse your dining options! The selection at 180 days out is usually very good, even though other guests have utilized the plus 10 perk.
I'll keep my fingers crossed that you get all the dining reservations that you want! And I think Shades of Green is a wonderful resort - I hope your stay there is spectacular!
