After a long flight and especially if you are traveling with small children you may be tempted to just say yes so that you can collect your car and go, well take note $10 - $30.00 over 14 days per day can work out at over �300.00 of your holiday spending money
My advice is that you do not need an upgrade, in the last 5 - 6 years i have never had a small two door economy car, yet each time I travel, a small enconomy car is what I book and pay for, see travel tips
You may also be asked if you would like to take out extra insurance, if you have booked and paid all insurance in the UK you do not need any extra insurance, however do make sure that you are fully insured to drive before you travel, i made this mistake on my first trip to the USA a number of years ago and had to pay over �700.00 at the Airport, had I paid in the UK at that time the cost would have been as little as �290.00.
If you have booked a flydrive without paying the car insurance forget the car and book another one with www.autosabroad.com note the quote you recieve from them is fully inclusive of all insurance and taxes, and can be as little as �140.00 per week
One last point do ensure that you keep your registration documents in the car at all times, and always carry your driving licence, it is the law in the USA that you are able to produce your driving licence or other documents at all times if asked to do so.
It is also essential that you take your driving licence with you, a photocopy will not be accepted and you will not be allowed to pick up your hire care without it, this has happened in the past do not make the same mistake.
