When I was an intern years ago I went to an event at a hotel in LA. I didn't know what room the event was in, so I approached the concierge, described the event I was there for, and he immediately whisked me to an upper floor, where I began to talk with the other guests. It took about 10 minutes for me to realize that while the people there were also interns, and we were in the same field, they were from a particular company, whereas my event was for an industry group. They had just been flown in from all over the country, so it didn't seem odd to them to see a new face (we were all new faces).

I eventually realized the error and quietly excused myself to look for the industry group meeting (which sadly lacked the delicious catered food and open bar that the first event had). Fortunately I made my exit before the higher-ups had arrived, as they would have quickly realized I was in the wrong place.
