Changing the bed linen in between guests staying over

[userloadsofnumbers]

I am going to try and write this as factually as possible. We have a lot of people staying over for various reasons. Partner A thinks the bed linen needs to be washed in between every guest, even if they've just slept in the bed for one night/a few hours. Partner B thinks that is unnecessary and doesn't have to be done every time.

Partner A also feels the house should be generally tidied before guests come over - stuff put away, surfaces wiped, plates/cups etc in the dishwasher instead of piled high next to the sink. Again, Partner B disagrees.

Partner A thinks 99% of people think like they do. Partner B says their parents and sister agree with them so Partner A is the weird one and has issues surrounding guests visiting.

So - who is being unreasonable?

Poll: YANBU - if you agree with Partner A
YABU - if you agree with Partner B

Partner A - correct
Partner B - grim

Changing sheets for each guest is a must, as is ensuring the house is clean and the guest room is tidy and welcoming. I'd like to say I always tidy the house too, but in reality that depends on how much time and energy I've got.

I know this is a zombie thread, but it reminded me of staying with a friend in Milan for 2 nights.
She had a regular turn over of visitors, and asked everyone to bring a cheap (£5) single quilt cover with them for stays of less than three nights.
We used the quilt covers as sleeping bags and she simply changed pillow cases 😅
