If there is a single man and a single woman in the itinerary, the travel agency has the right to adjust the couple's room or the guest will make up the room difference by himself.

if there is a single man and a single woman, the guest will have to make up the room difference by himself, but when there is a single man and a single woman, it will be expensive, so it will not be the price when the travel agency calculates the quotation, and it will have to be added. If you don't want to make up the room difference, you can only change to a triple room. Generally, if the husband and wife travel in the same room, but if there is a single man and a single woman, the husband and wife will live separately.
