Change guest numbers over xmas

[Abi29]

Hi,

my 2 listings are set to 1 guest only because we prefer it that way, even though each room has a large bed that accommodates 2 people.

I’d like to temporarily change this to 2 people for the Xmas/summer period. Is there a way I can change the number for specific weeks only? (In the same way the price or min. & max. nights can be custom adjusted)

I don’t want extra guests booking to stay outside those custom weeks.

Many thanks in advance!

Abi
