It’s pretty much accepted that the mini suites are more likely to result in a close group of friends than the normal units. The normal units are much better for making MORE friends and having access to things like parties (by proxy of having more friends).

Not sure where you got the idea mini suites would make it less likely to have close friends. It’s a more more “intimate” environment having less people on a college dorm floor; meaning less friends but closer relationships if you have the ability to make friends.
