I am a Brazilian, and I will travel with my wife and son to spend some days in California.
I will arrive in Dallas and take an internal flight to San Francisco. I will rent a RV (Recreational Vehicle) in San Francisco, and I will travel across California (Yosemite Park, Los Angeles, Disneyland, Monterrey).
After 8 days, I will spend 3 days in San Francisco in an Airbnb.
What address should I use in the Customs and Border Protection form, field 4?
