You give little information, so you can T give a specific answer.
Let me talk about my thoughts around saving money.
First, it is suggested to go to Tibet in the off-season. According to the existing policy, all scenic spots above Grade 3 in Tibet are free of admission (public transportation in scenic spots is inevitable), and the accommodation fee in peak season is no more than 50%.
Secondly, the ticket price in the off-season will be much cheaper, which can save time and play more scenic spots. But don amp Don&;t go to Tibet during the Spring Festival. When the ticket price increases, it is difficult to buy a train ticket.
Third, if your budget is limited, don&;t amp T rent a car. It It&;s cheaper to take a bus.
Fourthly, if you go in the off-season, it is recommended to go to Lhasa and Nyingchi, especially Nanga Bawa Peak. The probability of seeing it is much higher than usual. Other areas are either blocked by snow, or because of the season, the scenery is average.
