Ha! None of you "I never make reservations" folks should take a trip with my DW!!
I'm a "spin the bottle and head in that direction" type and she needs to have everything planned out 3 months in advance. So far it's worked out because we're doing short trips, but when we cut out for our "let's see America" trip. it may be a problem.
Of course, I can be just as rigid. We reserved a house boat on the west coast of Florida for our 20th anniversary and I had the entire trip planned out 6 months in advance. Totally destroyed me when the boat broke down on the first day.
