When booking a hotel online for 900 a night, does it include a deposit in addition to the room fee? Or should I pay a separate deposit after arriving at the hotel? Generally three or four stars

The number of nights written in the online booking is the number of nights. The deposit is paid separately. You will be asked to pay it when you check in and it will be refunded after checking out. Generally the deposit is less than 300. Catering depends on the configuration of each hotel. Some will provide breakfast, but generally not. You can call to ask before making a reservation.
