Splitting a room of 4

hey! interested to know others experience of
this.

To preface, I don’t expect nor demand that this will happen, just seeing what people’s luck is in doing so

Ive booked a room of four (4 beds) for a 2 night stay. but I see there are still a lot of rooms available in the hotel that night

in the event that rooms are available, do you think it be possible to ask for our party to split into two rooms in lieu of an upgrade?

how would you ask for this and get it without paying additional money? (the rate is already $800 a night)
