A mandatory company retreat where you have to room with a coworker is weird, right?

Ok, so my friend recently found out at work that they are doing a big company retreat this summer at a national park, however, co-workers have to room together. It will be at a hotel, but unclear if it will be nice. Oh and they are keeping it guys room with guys, girls room with girls.

But I was so taken aback by this when my friend told me! It's weird to have a mandatory retreat where you HAVE to room with someone you work with right? Has anyone dealt with this or have good excuses they've used to get out of work retreats in the before times? My friend is dreading this.
