but for him to not have to lift a finger to basically garner Bree and Sophies attention
Haven't played yet, but assume they're campers.
I went abroad once with a group of college students - I was a much older alum. One of our stops was in Italy, and a couple of the girls openly expressed that they wanted to hook up with a cute Italian guy while we were there. These were early 20-somethings in an advanced program - so not just dumb bimbos.
A couple of girls getting away from home - maybe for the first time, maybe because home is a controlling environment, etc. (like I said, haven't gotten into the story yet) - and wanting to hook up with a cute guy just to have that experience is something I've seen play out IRL (at least one of the girls on my trip was successful in her quest). So, while it might not be the most common thing in the world, it isn't exceedingly far-fetched, at least in my real world experience.
Saw similar things in HS band camp - those Alyson Hannigan "one time, at band camp" stories in whatever movie that was are also not that far-fetched based on personal experience.
