If you have a very attentive tour guide, they will help you adjust the itinerary according to the weather. Although some places are not as good as you imagined, it is still great. Be aware that there are various additional fees, entrance fees, and fuel fees after you arrive at the site. I later paid more than 500 US dollars in cash (including an extra 107 magnesium for the salt flat tour). Also, when traveling in a group, it is sometimes impossible to control the correct meal time. It is normal to miss a meal by three or four hours. You can bring some of your own food in your backpack.
