We were thre last February when days ended up being mostly 8s, but our AK day ended up being a 10(forecast was a 7, I think?). It was very very busy, but still not as crazy as some of those Christmas pictures. There were bottlenecks wee it was hard to move, though, so not too far off.
We had a solid plan, arrived early, hit our FPs, and got OUT midday when it got hot and crazy. We came back in the evening, and crowds were still high (closing time was extended the day before and again during the day),but we had (old school anytime) rider swap to use at FOP, did a mobile order at Satuli, and used dining plan tickets for ROL. So we got done what we wanted and just were patient moving through the masses.
I think our upcoming March trip likely overlaps with your friends—we’re coming from Ontario, heading down before March break starts but staying through part of that week. Several of our earlier days have also been bumped to very high predictions. I’m going to go over our plans with a fine tooth comb to nail down the smoothest plan we can have, but I’m confident we can still have a good time. I think with your planning your friends will still enjoy it, too—especially if they are willing to do things like get an early start.
