I want to do a summer road trip down the east coast of america, I want to start from canada and end up in florida but as i live in the united kingdom at the moment i am finding it hard to calculate how much it would roughly cost. I am going to be nearly 19 when the time comes for the trip and want to rent a car in USA plus see most of the sites that i can with maybe 2 or 3 other people. I am hoping to travel for about 3 week's to a month. From lookin on the internet i have found that there is no car rental company that would rent me a car due to my age even thou i have a full UK and internation driving lisence. Does anybody know where i could get a car rental from ( i know this is a bit early but its good to plan ahead) and also how much it would roughly cost for an average trip if we were to stay in motel's and cheap hotels?
