Don't ya think they work. I think they might, only if it involves frequent visits. I think one major advantage is since if I live in a Hurricane prone area, I might as well evacuate to her area without hotel spending. Plus her area might be a "home away from home" to you as well, and vice versa. Plus eventually once you decide to tie the knot you have to find a way to live with each other, I think I find that difficult. Plus it's also kind of hard to monitor, especially when it comes to cheating or or whatnot. I haven't been in one, but I probably would liek to try it out, mainly since I have a large discontent with my locals.
