I love traveling but I avoid couch-surfing like fire. I think is down to the kind of person you are.
Hostels are my time off. I can sleep in my bed as long as I want, I don't have to talk to anybody, I can pay and not ask/talk. Socializing is huge energy consumer. Hostel time is when I don't have to worry about a thing, relaxing and recharging.
Especially since the OP is working on the road. I would feel shitty being a CouchSurfing guest and immediately asking for the WiFi password because I need to fix something.
