Be prepared to stand up for yourself in a transaction with a hotel, an airline or travel agency on Monday and Tuesday. Know exactly what you're paying for, and don't hesitate to ask for the manager or take your business elsewhere. By midweek, traveler's luck is back on your side; listen closely for fascinating details and explore, explore, explore. Taking public transportation can be an adventure you'd never get in a cab or rental car. This weekend, your karma has a quick turnaround time -- do something sweet for someone and watch it come right back to you.
