Yeah, but its thinking of things I'm likely to enjoy that I may not even be aware of are options and researching the options for that activity and which providers are worthwhile that makes it time consuming. Some people enjoy that aspect. I don't.

EDIT: With respect to Airbnb, they're all group activities, which for the most part makes them less interesting to me. I'd like the idea, a map, tickets/bookings if necessary, but for the most part I'd have no interest in guided activities. I get that makes it harder to profit of because you're giving away half the work by telling users about the activity.
