As a fan of tropical beach town type environments, I concur that there needs to be more like this. I remember there was a sort of ‘spring break’-esque RP map being worked on a little while back but I dunno what’s happening with it, it’s been a few months since there was any news on it.
Apart from that, here’s a few similar ones that I’ve been using:
The Gmod Tower Lobby 2 map also featured an awesome beach town setting complete with a water park and fancy condos, but after Pixeltail games moved to Tower Unite, they removed the maps from the Gmod workshop. Would love it if someone could bring 'em back in Sandbox form sometime.
