WDW has numerous dining option that cost less and are better experiences. (For example, the buffet at Boma. Incredible food options at a better price and a much easier ADR to get. Plus you can explore the Wilderness Lodge and watch animals on the savannah.)
If you rarely go to WDW, then skip Space 220 and go with one of these better options.
Conversely, if you frequently visit WDW, then give Space 220 a try for something different.
