The hammer tours are really fun, especially if you have other people playing. The Evening Firefly one is really relaxing to play for some reason; I usually play that one if I need medals for some reason.
I haven't played the shark or firefly ones in a while but those are my favorite, I think.
I've been doing the gardening ones a lot lately, it's just chill and everyone I play with gets medals easily with it.
the hammer ones are fun too.
I feel like I'm forgetting a lot of the cool ones and I'm sad
I love the Tuna Kahuna and the Giant Dragonfly tours. Not only can you earn a ton of medals, but I think it's fun to catch all those big fish/bugs...even though you don't get to keep them.
I also enjoy the hide-and-seek tours, because they can be completed very quickly if you have 3-4 people playing. And you don't have to wait for the time to run out once you've earned gold, unlike in some tours.
In terms of personal enjoyment I really like the ore tours! Those are fun to play with other people, and when playing alone it's pretty easy to get all the bonus + special ore to get full points.
The Hide N Seek one by far !! I love finding all the different villagers (they’re mostly all so cute and I really enjoy meeting them.) Plus, I just find it fun to play it with other people too, even with the abundance of pitfalls !
I like the hide and seek one because it is cute and it is easy to pass this event quickly if you want medals. I also like the gardening ones. They are a great way to get some cool flowers for your town.
