I've been to parties where a few friends--the same people each time--would show up 2-3 hours late to a party and their house was only a 10 minute walk away. When I'd ask why they were late, it was the same reason each time. "Oh, we were watching a movie." A typical movie is 90 minutes long, so they would've been putting it on just around the time the party started. In general though, everyone was a good 20-30 minutes late, but a few people and myself would show up early to help the host prepare last minute food/drinks.
