The United States is very large, and every time you go somewhere it's different. This summer, I went to Yellowstone and chose an SUV, but I regretted it because the high center of gravity made it tilt heavily on the mountain roads... and all the roads were paved, so if you don't have a need for a lot of luggage, don't choose an SUV. Last year, I rented a BMW 4 Series to drive around the Grand Canyon area and it felt great. I stayed in Yellowstone for 5 days, 2 days at Old Faithful, 2 days at Canyon, and 1 day at Yellowstone Lake. The itinerary was not tight, so I just played around and drove all the roads in Yellowstone. Accommodation in Yellowstone is expensive, and the itinerary was not optimized, but the gas prices were cheaper than in the Bay Area. As for cash and credit cards, to be honest, I haven't used much cash in recent years. I only keep cash for tips. Throughout the trip, I only used cash once at a strange restaurant in Salt Lake City for one night, and also used cash to send postcards at the Yellowstone post office. Everything else was done with credit cards, including self-service gas and meals. It was surprising to find out at a gas station in Carson City that they explicitly did not accept VISA credit cards and had to use a MasterCard. I remembered trying credit cards at gas stations in Utah and San Diego last year, and this year's experience was really different, as many gas stations have upgraded ?
United States Q&A
It used to be smooth to pick up the car in advance no matter where, but this time at Hertz at Oslo Airport, I arrived more than an hour in advance and was told that the car had not arrived and I couldn't pick it up early. They asked me to pay extra to change the car or wait for an hour to complete the procedures. I ended up waiting for an hour. Ten days later, I had to go to Iceland and arrived three hours in advance. I was afraid of encountering the same situation, so I wanted the customer service and the car rental company to communicate the situation. The customer service asked me to cancel the order and place a new one, but I had to email the car rental company to explain the situation. However, I did not receive a reply from the car rental company in Iceland. Fortunately, picking up the car in advance in Iceland was not a problem, and I was upgraded to an SUV with 4-wheel drive for free. So, I have a good impression of Iceland this time, but a very bad impression of Hertz at Oslo Airport. They not only make things difficult and charge for miscellaneous items, but they have already charged me three times ?
