Monday is great for emailing the home office or calling a hotel to change a reservation: communication of all kinds will be crystal clear. If you're on the road with people, make sure to spend some time going over some basic ground rules of cooperative travel. A misunderstanding may have left a bit of bad feeling in the air, and this discussion will help clear it. While friday and saturday may find you feeling somewhat sluggish, you'll be able to work through this feeling with your usual tenacity.
