General information, including the date and time, funds remaining, population and star rating, and occasional specific information on your tower is transmitted in the top floating window. The buttons on the Control palette at lower left provide specific information on the hotel portion of your tower, outside elements like billboards, pricing of the rooms, and an evaluation of the components of the tower and traffic to them. Your tower is not just a hotel. Your tower can have attractions with a ticket booth and it can even have condominiums as many resort hotels seem to have. The low resolution screenshot doesn't do it justice but it gives you the general idea.
Diurnal time is simulated so there are night as well as day aspects to the tower.
The four seasons are also simulated and the speed of time-related changes can be controlled. You make money off the rent from occupied space and from occasional windfalls such as finding buried treasure when building underground floors. People occupy the available space depending on its attractiveness, accessibility and cost, each of which you control in various ways. People move in or out, affecting your income, depending on how well you handle these events. You can check on the profitability of each.
