I know i'm in the minority when saying this but though I've never stayed at one (there was a time when I did consider it) I would never stay at one knowing what I do now. Every person travels differently, I get it but I can't justify going to some whole other country just to stay in one place doing activities, eating food that I could do/eat at home. For ME, it's a total waste of $$ and time. I want to experience the local flavor. I'm also a tipper and these places will not allow you to tip. I would also have enough sense to research the area I'm traveling to and find safe places to stay, NOT look like a tourist, and support the local economy (especially in an area that is economically struggling).
Just things to consider if you choose to go this route:
