Plan for a little extra time to get up and running tuesday and wednesday. Starting the day at a small cafe gets you in the spirit of your destination: have what the locals are having. Anything that's on your itinerary toward the end of the week is definitely going to get checked off, and then some. A little romance may even find you on the road now. Eat regular light meals and drink plenty of water this weekend; overindulging will slow you down.
