Not a whole lot. We know where we are going, of course, and how we are going to get there, and when, sort of. But that is about it. If it is a timeshare or a cruise, then we know where we will be staying, but if it isn't, then the lodging may be postponed to the last minute. All a characteristic of a 'P'-type from the Meyers-Briggs personality type indicator and I am about as strong a 'P'-type as you can get.
