I think USH has a lot going for it
1) Theme parks are still up after the Pandemic and are cheap vacations for most families
2) Nintendo is Disney of Video games, people that LOVE Nintendo.....love it.
3) The land is getting almost across the board amazing reviews, Star Wars Galaxy edge didn't even get these high marks and they have an even more impressive ride but the land was hit or miss. This land has it all a fun ride, cool meet and greets, food you can put online to show off to others and the land is just soooo alive and the lines for the band games show that people are seeming to love these little inactivate parts
4) The Mario Movie, its not out yet but I can tell you that film is easily going to hit a Billion and push even more people in the land
5) Disney on both coasts has cool little things being added but nothing as cool as SNW, so i think many are going to travel to USH over one more Day at Disneyland or skip Disneyland for SNW.
6) HHN, last year was not a perfect year but very loved and from the constitution and rumors we have another great year at hand. So I think this years HHN will have more sold out nights then ever before and many sold out days because so many will be doing both the event and going to the park in the day.
I could be wrong but as someone who daily checks the app, I've just never....never seen the park as busy.This is also before we even know what the summer entertainment looks like, are we getting more Plaza shows to draw in more people? Or maybe if USH was really liking free money a Nintendo event of some kind. Either way, its safe to say this will be USH busiest year, until DK land opens
