First time driving in the US around Seattle and Olympic National Park, it was great! Few cars, but m

It was my first time renting a car in the US. At pickup, they asked if I needed to purchase various insurances, but I didn't. Wanted a small Ford, and with the staff's help, successfully changed the car. Midway, had a flat tire, and my phone had no signal. Communication was difficult when I got back to a big city, so I decided to go to a rental point for face-to-face help. The staff helped me switch to a new red Dodge. As for the tire, they said someone might contact me about compensation, but friends said it should be fine. When returning the car, there is no shuttle bus from 01:00-04:00. As I had an early flight, I returned the car around 5:00. There aren't many 24-hour gas stations near Portland, so I recommend checking Google Maps and calling ahead to avoid last-minute rush. Returning the car was very smooth; they just took a look and printed out my receipt. Overall, it was a good experience.
