Is it cheaper to travel to Los Angeles with a group tour or a self-help tour?

Now the United States actually gives a lot of free time for group tours. For example, Hawaii, Los Angeles and Las Vegas usually have one day's free time, while other cities sometimes give half a day's free time.

The problem with free travel is that you have to arrange your own itinerary, go to the American Consulate in official website, fill out a form, apply for an interview, apply for a visa, book your own hotel and air tickets, rent your own car, hire your own local tour guide and buy your own tickets.

If you join a group, you will save a lot of experience and money. Generally speaking, under the same route and standard, the United States will spend at least half as much as traveling with a group, and the route span in the United States is large. If you go to Hawaii on the east and west coasts, you have to go to many cities and take care of every car and plane in the middle. Another factor is security considerations. If your English is still poor, it is safer to join a group.

It's best to travel with a group for the first time in a region, because I don't understand that unless I read a lot of raiders and travel notes, it may not be better than the route arranged by the travel agency.
