As much as you might want to dispense travel advice on monday, resist the urge. Others like to think they know what they're doing (whether they actually do or not), and your well-meaning tips won't get the audience they deserve. Midweek, you might feel hesitant about the next stage of your trip, but go on and take a leap of faith. Good trips can require great courage sometimes, and you don't need to have everything figured out ahead of time. Friday and saturday, watch for trouble with traveling companions (especially if money is involved). Don't get suckered into impulse buys, package tours, or anything else that sounds too good to be true on sunday.
