The hotel sleeping bag is detachable.

I think it depends on what car you drive. If the space in the car is small and the air circulation is not enough, you can't spend the night in the car or you can barely sleep but feel uncomfortable, there is no doubt that you should not drive to investigate. Because the examination is not a day or two, it is difficult to concentrate on driving and it is not safe enough for lack of sleep. But if you drive a car with a lot of space. If you can sleep in the car and feel comfortable, of course, it is cheaper and time-saving to drive to investigate. As long as you have a navigator, you won't get lost when you visit other provinces. Leave if you want, and rest if you want. It not only saves the cost of staying in the hotel, but also saves valuable time. You have to visit several provinces. No matter where you go, you have to spend a lot of time buying tickets and waiting for the bus. Trains and buses are crowded. It is troublesome to change hotels, so we should always consider the price of staying in hotels. Cheap hotels are uncomfortable, and good hotels are not cost-effective. Because you're not traveling for a short time. You can enjoy the scenery along the way by yourself and meet many new friends on the way. It's easier to see, hear and understand what you want to know when visiting. Don't worry about when to get up, when to take a bus or take a taxi back to the hotel. In some remote places, not only are there few buses, but even taxis are not visible. If you drive to investigate, it will be an unforgettable trip. Of course, be prepared before you leave. For example; Get a sleeping bag or something, sleep warm at night, change clothes and pants. A refrigerator, put some food, medicine for stomach trouble, mosquito repellent, sunscreen or medicine that must be used at ordinary times, prepare some books and music that can be put in the car, and a blanket big enough to lie on the ground, so that you can have a good sleep in a beautiful and sparsely populated place. Prepare more big bottles to hold water. It is recommended to stay in a mid-range hotel for one or two nights a week, and use the time to wash clothes, recharge, fill up drinking water and buy necessities. Don't drink water while driving to avoid diarrhea. The most important thing is that you can't drive to inspect until your driving skills are good. Before you leave, collect the maps of the provinces you want to go to, check whether the maps in the navigator are the latest version, if not, go to the place where the navigator is sold and find someone to help solve this problem. Look at the map, mark the places where you can spend the night, and get to know some local customs. It's best to choose a safer place for the night. The more carefully you do your homework before you leave, the smoother your journey will be! I wish you a pleasant journey in advance!
