想o係北美旅遊, 邊度比較適合唔識開車既人作自由行呢??

Because you are studying in East coast, why dont you go to New York City, you can go to broadway, times square to shopping and go to watch a play. There are lots of famous play , mama mia is cool, but i am not sure do they still have this play offer! And the transportations are very convenient in NY, like subway and buses.
In the other hand, if you want to go to west coast, will be tough ,because no car= no foot. You cannot go where you want to go except call the taxi ( but very expensive) . I suggest you go to Las Vegas , lots of casino, but if you are under 18 or whatever, you cannot go inside, but there are lots of show and big shopping mall, one of the example is Treasure Island. And at the outside of The Belagio Hotel there is a big fountain, and at night there will be a music fountain show.
San Francisco is also a good choice, you can take the tram, and go to Golden gate, you can also walk through the bridge for free ( if by car, round trip is $5) They have a nice view espically in sunset. And with the pacific ocean, the mood is so good and relaxed.

In NYC,must go to statue of liberty, although right now you cannot walk to the top of statue, but is still nice, you can enjoy the view between the islands

NYC, because it already has a very well developed public transport system and in fact you can hardly drive there because of the severe traffic jam, it will be a lot easier if you use the subway or bus system instead of driving on your own.
