It's actually fun, you can go out and explore or chill and watch movies and be there to see your partner return sloppy drunk in the evening lol! I'd never ask if I didn't have a +1 of course but as long as my partner is doing their own thing and is independent, sometimes it's nice to have a partner in crime to travel with you several hours to a strange town.
