Sleeping with strangers

Tonight I'm getting ready for my five days away from home for week 2 of professional development. All of us teachers have to arrive there tomorrow, stay for five nights, and leave on Friday. The place we're staying looks nice, and I'm sure the professional development will be at least partially worthwhile, but the truth is -- I'm dreading it. I think it's a lot for the school to ask us to go away for five nights when we won't even have our own hotel rooms. We're sharing, three people to a room. I need my alone time to recharge my batteries, and I won't have that, so I'm really nervous. I also usually have a personal policy not to spend time socially with co-workers until either they've left the job or I have, and we don't work together anymore. But this week I'll be sleeping with two of them, which upends my whole policy! We'll see how it goes.... :/
