Hello Evelyn!
I had the opportunity to dine at the
Space 220 Restaurant located in EPCOT during my last vacation and the experience was out of this world!
Dining reservations can be made online 60 days in advance. If you prefer, you can also
call for Disney Dining reservations. Please note if you are a guest staying at a
Disney Resort Hotel, you have the opportunity to make dining reservations for up to 10 days of your vacation, 60 days prior to your check-in date. (For example, if you are staying at a Disney Resort Hotel beginning December 1st, your dining reservation window would open on October 2nd. At that time you are welcome to make dining reservations through October 11th or your reservation end date, whichever comes first.)
The Space 220 Restaurant is an extremely popular restaurant so I recommend making a reservation as soon your dining reservation window opens. If you are not successful, continue to check back from time to time in case there are cancellations.
As an alternative, you can also try to get a reservation to the
Space 220 Lounge. The experience is similar but you will be sitting in a lounge vs. the dining area.
Good luck with securing this reservation. I hope you can soon say "Mission Accomplished!"
