It is not common to go to a hotel without a reservation so I will only cover the reservation aspect. Along with reserving a room, I will cover checking in, checking out, room service, and wake up call.
Making a Reservation
When you make a reservation, call them and tell them you want to reserve a room. Or, you can start by asking them for a price.
Hi, how much are your rooms?
Hi, what are your rates?
Hello, how much is a room?
Our rooms start at $79 for a basic room.
Our rooms start at $79 for a standard room and go up to $300 for a suite.
Ok. Can I reserve a room?
Hi, I would like to reserve a room.
Hello, can I reserve a couple of rooms?
The first thing they usually ask is the dates you want the room and the duration.
