According to the calculation method of uniform charge, the yacht fee will not be changed due to the restrictions of epidemic prevention measures. For example, if 100% of the passenger capacity of yacht is 40 persons and the price calculation method itself is a uniform charge for 40 persons or less, the charge will remain unchanged, that is, there will be no refund of the cost of additional people, regardless of whether the last number of people on board is 75%(i.e. 30 persons)after the current limit or narrowed to 50%(i.e. 20 persons)in the future.
