When you buy the full tank, the price may be close to the going rates locally, but that's not the gouge. The gouge is that you get no credit for whatever fuel remains in the tank when you return the car. Instead, you donate it to the rental company. So unless Avis, Hertz, or Enterprise is your favorite charity, this option is a nonstarter. And when a rental company fills the car, it typically charges two to three times the local price per gallon (or liter).
We've compiled a list of reputable companies with rental outlets statewide. Check charges in advance; there are lots of options including insurance coverage and extras, so be sure you get what you need and know what you’re paying for before you drive away. Companies may also offer a pre-pay fuel plan with discounted prices, worth considering if you know you’ll likely use up at least 1 tank of gas.
Don't take a sleeping bag unless you're actually going camping. They're useless. Most hostels won't even let you use them. Don't pack too many clothes – remember, you'll buy things while you travel. Don't take a huge first aid kit. You really just need a few necessities. Don't take more than three pairs of shoes. Don't take more than two pairs of jeans. But do take soap – most hostels don't supply it.
“I’m a firm believer that everything you need for a trip — whether it be three days or three weeks — should be able to be packed in a carry-on. This is simple once you master the art of layering your clothes. Choose a color combination for your attire and pack only pieces that match this so that you can mix, match and layer to create different looks (instead of packing completely separate outfits).”
