I too skip the coops if there's too much other stuff. The kegs, preserve jars, and mushroom logs are a different beast though. Winning a prize ticket isn't worth delaying any of those production cycles by a day. I'm also maxed out on friendship with everyone, so the ice festival is all about losing 10-13 hours for a prize ticket.
The night market on the other hand... was mostly spent fishing using wild bait. Feast of the Winter Star coming up. Will probably participate even if I already have the Tea Set.
