Plaza Hotel , good morning . Leo speaking .   Ah yes , I'd like to book two rooms for myself and my father . Could you tell me the cost of a single room per night ?   Certainly . A single room is 120 dollars American , per night .   Fine .   And when would you like the rooms ?   From the 25th to the 28tri of September .   Arriving the 25th of September and leaving on the 28th ? Three nights ?   That's right .
