Excuse me, do American hotels have hair dryers?

I just got back from America, and I can tell you something:

Hotels in the United States basically have hair dryers, but hotels in the United States require environmental protection, so there is no toothbrush, toothpaste and slippers, so you need to bring them yourself; The power supply in the United States is also different from that in China, but if you just charge the camera and mobile phone, you can use it directly, and you don't need to buy another power adapter. Everyone can only bring five thousand dollars into America. If you exceed this amount, you must declare, one cigarette per person and one bottle of high-alcohol per person; When you fly in America, you are not allowed to lock your checked baggage. If your checked baggage is locked, it will probably be pried open by the airport, so you should take valuables with you. The weather is different in all parts of America. Hawaii, Los Angeles and Las Vegas I went to were extremely dry and hot, and my skin was sunburned. I suggest you bring more sunscreen and replenish more water. Chicago is better and wetter than these places, so I don't know about other places. It's best to use a credit card in America. If you don't have a credit card, you can apply to the bank for a new card with VISA logo, so you can swipe your card in the United States, and you have to pay a commission to purchase foreign exchange, otherwise you can't use it; I suggest you keep everything simple when you go to America. You can buy it in the United States, and the domestic price is relatively cheap.

I can't think of so many others now. If you want to know anything else, please leave me a message. Have a good time in America!
