I don't imagine there will be a huge crowd there on a Monday, even during spring break. As for the weather, March is tricky. It should be nice (probably highs in the 60s or low 70s), but it can get chilly and windy (we even had snow during Passholder Preview Day a few years ago).
Just keep checking weather.com.
Truth! While the technology had me intrigued, I wasn't terribly excited for this. After riding it last week I can say it was actually quite fun! It's a much better use of space than Flying Tires, and everyone seemed to be enjoying it.
I felt the same way about Mater's Junkyard Jamboree until I rode it.
Panda Express is one of those places that I'm OK with, even though it's not amazing Chinese food; that being said, the new Chinese offerings at SFMM look pretty good. As for Revolution, it's great to see the ride looking "fresh" again, and I hope the new trains make it "good" again.
I'm not sure about all this "VR" stuff, either; my past experiences with this technology left me feeling nauseated. Still, I imagine "flying through Metropolis" at SFA would be better than over a vacant lot.
^ & ^^ I knew nothing about Deadpool until all the comic-book fans went nuts when the movie was announced. I enjoyed it, particularly for the character of Deadpool himself (not so much for the story).
^Thunderstorms are a fact of life here during the summer, so I don't think it much matters which of those days you choose; any of them should be pretty hot and humid.
