Hotwire offers nationwide car rentals with prices starting at $8.95 per day, as seen on Travelzoo. (We found this rate from Miami, FL, (MIA) on April 12 and return on April 19.) That's a buck under last week's mention and the lowest daily rate we could find for select rentals by $2. Fees, insurance, and taxes are additional and may be substantial. A minimum 2-day rental is required and blackout dates may apply. Book this travel by March 31 for rentals through April 30.
