To Info, I think the guitar idea is great. Get one and someone may be inspired to play it and these days you can learn the basics online.
We have TVs, free wifi and lots of books. The best entertainment happens during breakfast where we chat and share stories. We sometimes play games with our guests. I also have a bowl of snacks available all the time.
Hi, another important thing is to always be the host that offers the best smile. I also find that providing things like extra toiletry helps. Just cheap toothbrushes, toothpaste and deodorant because people sometimes forget them.
