Of course, it is better to travel to the United States by car, because you can have a lot of time by car to see the beautiful scenery and eat the delicious food you want. There is no need to join a tour group when traveling to the East of the United States, and the public transportation is developed, so I can totally handle it myself. There are many national parks in the west of the United States, and each scenic spot is far away, so renting a car and driving by car is the most suitable. The tour time of a park is 1-2 days, so it is better to control the time by car and it is convenient to walk. Whether driving by car or traveling with a group, the cost of each person is relatively small when there are many people. It is recommended to find more friends to play with when you leave. Recommendation for traveling with a group or renting a car: Delta Travel.
