How does hotel tycoon 2 increase profits? Good idea, it doesn't matter how much it costs!

I think there are several places that earn the most money:

1 fitness club, super rich, every room should be built, more than n people go every day, each room need not be too big, but the facilities must be the best. For example, every fitness equipment should have a reception desk at the door. As for the masseur's beauty room, three beds in one room is absolutely enough.

Swimming pools, whether outdoors or indoors, are very profitable. Although it covers a large area, it is not expensive. My swimming pool is set for 70 hours, which is quite profitable.

Outdoor climbing equipment. Building a 50,000 yuan can be seen in one month, which is quite profitable.

Cake rooms, art rooms and jewelry stores should also be built. The discount I set is 10%, and there are many customers.

Bars and cafes are also built to make money, but certainly not as much as the first four.

Pure handwriting, you don't get any reward points. . . .
