Change of plans

I'm a "planner", so I don't adjust well to change. I just found out that I'm not flying out next Thursday. My business trip will be delayed for one week. Now I have to re-book all my tickets and reservations. I know "it happens", but it's going to cost me some money out of my own pocket. Yesterday I had pre-paid for a hotel in Paris, but at least the penalty fee is not much, however the hotel is booked for Easter weekend. Now my hotel hunt begins again. My flight is triple the cost on the holiday weekend, but the company should be covering that. I have yet to tell my other friend who bought his plane ticket from his own pocket, eek. I think I will move my vacation weekends by one week, unless I decide to swap it by going to Paris before London. Back to the drawing board...
