I am going to the United States in February. The place I am going to is Los Angeles, Las Vegas, and San Francisco. Can anyone help me? Tell me everything you need to bring

I went there at the end of November and just came back from there! The sockets in the United States do not necessarily require a converter plug like those in our country, but because the voltage in the United States is only half of ours, it is easy to run out of power. It is said that the function of the converter plug is to charge it faster. The hotel does not provide toothbrushes, toothpaste and slippers, you must bring them! Hair dryers are available in all better hotels. If not, you can ask the front desk to get one you don’t need to bring (some SB tour guides will ask someone to bring a hair dryer...). You must bring money. In addition to large one-dollar (USD) bills, it is best to prepare a few pieces of change to facilitate tipping. If you have large purchases, there is no handling fee when you bring your VISA card. Since you go to the casino to bring a lucky item... don't lose a lot like me... By the way, some people say you should wash your whole body before gambling, and some say don't wash yourself or you will lose completely! I think...the latter is more correct! The LAS tour guide will definitely take you to the discount store for shopping! Buy more! Absolutely worth it! I'm sad that I don't have enough time to shop... It's definitely not a loss if you buy more like NIKE COACH, and there are also perfume sets such as LANCOME and Armani! Great value! It’s a great gift for everyone!

By the way, the most important thing is that long-distance flights are very tiring. If you don’t sleep well, bring eye masks, earplugs, slippers and an inflatable pillow. It is absolutely necessary (there are earmuffs and earplugs hidden in the back cabin of the plane) You can take it, but it’s better to take it with you.) It’s a good idea to buy some whiskey and some skin care cosmetics you need on the plane when you return home, and the price is affordable! By the way, the tour guide should also take you to buy health care products and the like. You can buy some. My mother bought a box... Although I don't know if it is useful or not, the selling price in China is indeed much higher. These are different opinions. It is better to bring two cameras. If you take too many photos, the battery of one camera may not be enough. PS: The Jiuquhua Street in San Francisco is very beautiful when you go to the highest point and take pictures. As a friendly aside, you may be asked if you want to go to the self-funded performance at LAS. It costs 99 US dollars per person (I guess the tour guide paid for it), but the best seat is indeed in the first row. There are many topless beauties, but for me, the girl added I'm very tired... I fell asleep on a few programs... If you haven't watched it, just watch it. If you have, just use this money to gamble! I've tried my best to be as detailed as possible~ If you have any questions, feel free to ask as long as I know
