Let’s say this is MY top 5 list:
5. Napa Valley and wine tasting
4. Surfing holiday in Hawaii
3. City of Lights (Las Vegas)
2. San Francisco and the Silicon Valley
1. La La Land (Los Angeles)
I’ve visited these places using DMC services: https://www.insiderexperiencedmc.com/.
But I’m sure there so much more to see in the USA. My next choice will probably be some of the national parks or protected areas.
