We went on a Spectro night and watched the parade, then rode four attractions with no waits - Jungle Cruise, Pirates, Splash and BTMRR. JC and BTMRR were very cool in the dark.
I wouldn't miss Spectro. We went on a Sat night in Jan and had a blast. I didn't find it overly crowded and I am really crowd-sensitive ( a new word in the disney dictionary). We ate at LTT and then went right outside to see the parade. Lots of fun!!!!! Epcot was ridiculously empty on that trip as well.
