Hi, Leslie. We only offer streaming, as we cut the cord years ago at home and I don't want the added expense for something that expensive that we personally will not use.
We do have house accounts for Amazon Prime, Netflix, HULU, and SLING (for ESPN, ESPN is the most common deal breaker when it comes to TV services and booking. SLING offers more than ESPN), because these are things we use at home. Guests can log in to their own accounts, if they would like, but that rarely seems to happen. When they log out, which we do remind them to do in our check out check list, it does mean the next guest will have to log back in. In those instances I ask guests to call me so can walk them through it, in case we have changed the password or something, as the same accounts are used for our home devices. It has worked reasonably well, though some of our older guests find it a little confusing. Most of our guests tell me that they aren't vacationing to watch TV and it isn't a big deal. I will point out though in our market we do not have as many children visiting as you might, say, near the beach or Orlando, for instance. I would think those kinds of locations might need cable to be competitive.
That said, I do not flag cable/satelite as an amenity we offer in our Airbnb listing, though we do on other sites. This is because on other sites you have an area to explain, Airbnb doesn't, so I don't flag it because I don't want to mislead people. In this way it manages expectations.
At our vacation rental we offer the things that are important to us as home owners who sometimes live there. I suppose if we got enough feedback saying people wanted it or were not booking because we don't have it, we might consider adding it if there was sufficient return on the investment. However, we stay pretty booked in-season and pretty well in off season too, so I don't think we will be offering cable any time soon. Hope that helps ;.)
