We're just back from WDW and ate dinner at Sci-Fi w/o a PS and with no wait. We didn't need PS's at all for this trip, the only exception being the first night we were there--January 2nd--when MK was still quite crowded. Instead of sit-down, we ate that night at Cosmic Ray's, which was just fine. We ate at several other PS-style restaurants all over the world for both lunch and dinner and didn't need a PS for any of them (altho we had a couple, which were completely unnecessary).
The Sci-Fi is adorable, btw. Our waitperson (Marsha) was wonderful.
