I went through formal recuitment so I havent been on your side of it, but I can give you an active's POV. I cant guarentee it's the same on your campus, but for us, when sororities had COB events at the same time it was fairly common for girls to split time between more than one event. Events usually ran from 6-8 or 7-9, and girls would "make the rounds" to the events of the chapters that they were interested in. In general, many of the informal recruitment events were so casual (ex: game night, making crafts, themed food/drink nights) that girls could come and go as they pleased and as their schedule allowed. As long as girls came to more than one event, spent a suitable amount of time, and acted sufficiently interested, I dont think not staying the whole time was ever held against them.
