Need a rental car for your honeymoon? Look into Priceline’s Name Your Own Price deal and place a bid as low as you want. Worst case scenario: they say that your bid is too low, and you can re-bid again with a higher amount. Try it, it’s fun!
You can also use Priceline to bid for your flights and hotels, but usually people want a bit more control over those aspects of their trips. However, who really cares what company you use for renting a car?
(Actually, I guess some people do like to rack up loyalty points by using the same company each time, but shhhh.)
On a related note, if you’d like to rent a car in a foreign country, make sure to check that country’s requirements about whether your home country’s drivers license is sufficient or whether you need to get an international one before your trip.
