I love Toy Day because the music has been the same since the first game!
And least favorite would probably be Festivale bc Pave is an a-hole and you spend a lot of time looking for certain feathers if you're not doing it w a friend and the furniture you get for all of that isn't even great like I was expecting some super awesome rainbow feather furniture but no hahaha
Looking forward to Halloween mostly for the items - I'm really tempted to do a fully Halloween-themed town. Festivale was all right. I like the furniture set, but it was very tedious to collect. Kinda have the same opinion about Weeding Day: I'd really love some of those items, but I doubt I'll be able to get them outside of buying them.
