I think that the water well adds a nice touch to towns. I wouldn't recommend the campsite, unless you plan on campsite resetting to find dreamies. It was a complete waste of space for me, because I didn't get a single dreamie from it.
Definitely the campsite. It's excitement never gets old - and, obviously, it's a way to get your tenth villager if you haven't started playing online yet.
the yellow bench. i dont know why i think because it was cheap? i did want a fountain but(back then) they were to expensive but i think a campsite is a good starting pwp
I started with the cobblestone bridge, then design-board, fountain, streetlight, fence, campsite, streetlight, lighthouse, windmill, geyser, fire pit, flower clock...
Something like that. Just whatever I feel like fits with my landscaping up until that point.
I think the campsite is a good PWP to start early with, even if you don't hunt for dreamies. It's fun to get visitors and if you want to keep changing villagers like I do it is a really nice way to get villagers.
