I enjoy camping more than the hotel experience, so I'm sort of on the fence with this one. I think I'd only want hotels if, and only if, they came with more vacation-like content and even then, also only if the spa-day stuff worked full-service on hotel lots because I don't see the point of staying in a hotel unless it has all the bells and whistles (IRL bias here).
I didn't think the hotel-like lots in vacation worlds were all that cool in either TS2 or TS3, so for TS4 I would prefer they didn't do it all unless they were going to do it much better than they have in the past.
