Scott may have hit on the true purpose of the question. Personally, I would not put anything like an Echo or Dot in the vacation home. Put a decent radio and TV in it, and be done with it for supplied entertainment gadgets. People can bring their own Echo devices, tablets, etc, as we do.
What most vacation homes, B&Bs, and even hotels need is DECENT INTERNET SERVICE. I have never stayed anywhere where I found truly quality internet; meaning at least 50Mbps, dual-band speeds. I often cannot get a decent, consistent, and clean stream of video on a tablet as I can at home. We can stream from our Netflix and Comcast accounts lots of programs on tablets (even from our home server) , but poor internet that's barely usable for email, doesn't get the job done. Also, is why we have wireless hard and flash drives with media files on them; so in case the locale's internet signal really sucks we can create our own signal from which we can stream media.
