[BY DESIGN] Generic lot types prevents Sims from visiting the lot

I actually take advantage of this feature.

I created an old 1 BR 1 BA fisherman's shack on an empty residential lot in Brindleton Bay and re-designated the lot as Generic. My Sim resides in Willow Creek but she is able to travel to this cabin for overnight or multiple day visits, eat, sleep, cook, use the bathroom facilities, etc. I mainly used Build/Buy items from Outdoor Retreat to give it a rustic feel. It's sort of like having an unofficial vacation cabin. My Sim is able to invite others to this cabin and they will show up and even stay overnight, but no other random NPCs will enter the lot. I have a similar Generic lot I made in Windenburg (the Mid NoWhere lot) that is just a campsite with some landscaping and a fire pit. My Sim can place all of her OR camping gear, sleep overnight, use the fire pit, etc., without having to worry about random NPCs trying to use her tent.

I plan on creating a similar Generic lot in Sulani as soon as I add Island Living.

I know I am getting a little off topic here, but I just wanted to point out some advantages of having Generic lots as they are & ways to enjoy them in game-play.
