With the right gal overnights can be a lot of fun, I used to enjoy them with my 2 Pittsburgh ATFs, sometimes at their place, sometimes at mine (when the wife was out of town) and some out of town trips (NYC, Philly, Miami). More expensive obviously than typical get togethers but always more fun, well worth it, and memorable. Of course, since they were with ATFs, women I had seen over 100 times each, there was a connection there and we all loved the extra time together that an overnight provided.
