Thanks everyone, but it turns out I can't do anything and boy, am I bummed right now. I didn't say that the day in question is only 2 weeks away, but since I'll be solo, I figured I'd have no trouble making plans. I chose Yak and Yeti, but their first opening was at a time that conflicted with a FP+ for a show. "No problem", I thought, just change the showtime. Boy, was a naive thinking I could do that. Turns out that all FP+s for that day for that show as well as for another that I was thinking of changing are gone. After all the years that I've chuckled at people getting their FP+s early, thinking "Boy are they dumb-they can wait!" Turns out I was the dumb one, and Yak and Yeti's done.
