I’m not sure what low attendance you have read about. I was there Feb 7th & it wasn’t low attendance. Last year I did Jan 30 & this year was definitely busier. Now the weather was much better this year than last. But I wouldn’t be a bit surprised if there aren’t sell outs because Disney is inching up the admission numbers. Last year, even with sell outs, people reported feeling the parks were near empty. This year, not selling out, but not many are saying the park feels empty. On our date, it never felt empty, but more like a “level 1” crowd.
Personally, I think these are pretty good money makers for Disney. When they first came out with the after hours events a few years ago, the chatter online wasn’t good. No one was going to go. Now, people are anxiously awaiting new dates. I think new dates will show up. Only question is when.
