No issue with that according to our local Comcast folks. We had them run a second line to our detached listing. It’s all one address, all one bill. There is a second black-box in the listing so that they can watch different things than we are watching.
We had one guest set who complained in their review that our WiFi was too slow for them to stream their own things. Awwwww…. too bad. They also complained that the listing was too close to the main house (20 feet) – maybe they are into really loud sex, who knows. Also complained that they didn’t have access to the hot tub (pool isn’t enough?). So I discounted everything that they said!!!
