1. Travel at night
Whether you travel by plane or train, booking an overnight trip means one or fewer nights in a hotel, hostel, or home rental. Plus, the fares for red-eye flights and overnight train rides tend to be less than travel during peak times. Worried you won't get a good night's sleep? Consider using miles to upgrade to a premium economy seat that offers more room to recline, or splurge for a cozy sleeper car on train trips that could end up costing less than a fancy hotel.
