At the Hotel 在旅館

I'd like a single room with a bath.
    Could you reserve a double room for me?
    I want a room facing the sea/south, if possible.
    Do I pay in advance?
    What time do you serve meals?
    Can I see the room please?
    What is the latest check-out time?
    How much is a room for one night? What's the rate for a single room?
    I'd like to check out（I want my bill）.
