I had been thinking of going tomorrow. Sundays are my usual day since it is normally less crowded than Saturday. I also still have 3 Sip & Savor passes for the Lunar New Year festival that have to be used by Monday.
I figured tomorrow might be even a little less busy due to the Academy Awards starting later in the afternoon. So those who wanted to watch it probably won't wait around if they get a higher boarding group.
But now it sounds like a certainty that it will be raining all day tomorrow. This morning, the forecast showed showers starting around sunrise, and continuing into the afternoon. I suspect that many, like myself, who don't particularly relish walking around in the rain, won't bother going for the 8 AM "lottery."
While I could perhaps work around spending time at the parks in the rain, I don't relish the idea of driving to & from
Disneyland in it. Not to mention I wouldn't mind sleeping in tomorrow, especially if it's raining, so I'm starting to lean against going. For those willing to brave it, I think the "guaranteed" groups might last a little bit longer, and even more likely would be the backup groups being available for lots of minutes.
