Technically, you do not NEED a reservation for Space 220 but…It certainly is recommended!
Getting reservations for Space 220 is no different than any other restaurant in Disney, it simply requires you to make an ADR (Advance Dining Reservation).
– The Restaurant – The Lounge
When it comes to securing reservations for the Space 220 Restaurant, the good news is that it’s SLIGHTLY easier than the lounge.
This works great if you’re staying at a Disney World Resort because, unlike locals or guests staying off-site that can only book restaurants exactly 60 days before the date they are booking.
