That is what many folks are observing, including friends of mine who are in the industry and trained observers and have been visiting parks that are not very crowded at all and yet there are long lines for MM+ kiosks and long queues for attractions that only had them on the busiest days before.
I'll take one of my friends, who has spent a lifetime working in the business, and their opinion over 87 posts on a forum like this one because even a crazy Disney maniac guest that would be a member here still doesn't know ops like someone who has been living it for years.
So, yeah, I know the lines are artificially inflated. It really hasn't been a big deal because the last 3-4 weeks are basically a dead period, but things start getting busier this holiday weekend and they don't really slow down all that much until post Easter, which is very late this year.
