one friend and I have finished our career this year and we are planning to do a road trip in the USA "to celebrate it" or something like that. But we actually don't really know how things work over there, I mean we have thought things to do very briefly but we know nothing about the distances, prices and things to do in the middle... I have already done road trips but just in Spain and France
Our idea is to go to NY and go down to Miami, go to the spring break (we have seen it so many times in American movies and tv shows that we would really like to see it in person... and party after all our study of course) and from there go to California.
Is it possible to do all this in 30-40 days?
I've looked some car rental prices on the internet but how much does normally costs over there? ...to see if their good prices or not. Are there taxes for being under 25?
how much money we will spend in gas for such a huge trip approximately?
and for last could anyone recommend me a good USA travel guide?
thank you and sorry if I wrote something wrong in English (I hope is good enough)
