Can I get shampoo and shower gel from Shangri-La Hotel?

As for clothes, bring something suitable for the weather there, and don’t miss any medicine. It's best to prepare some fever-reducing and cold medicines. If you personally don’t want to eat the food arranged by the hotel, you can also bring what you want to eat, but it is recommended not to have too many snacks. Traveling light is the only way to travel. Regarding the issue of cheating people, for example, if you buy tickets or something, you have to go to the designated place. Don't believe too much in sales pitches from strangers.

There should be specialty shops in the local area. I suggest you check it out.

As for the title of the question, I can tell you that hotel rooms everywhere are basically equipped with the things you listed above. Some high-star hotels also have laundry rooms, but they are for additional consumption.

I wish you a happy journey!
