how did you ask for late checkout?
I ask on the day itself. for noon checkout. make up some reason. never been rejected before. manhatten mgmt also allow.
most noon is the standard. they put 11am cause put noon, ppl 1pm then checkout. there's only a handful of mgmt in jb, even tho there are different hosts. the sop is all similar.
most of the time is the host dont wanna cause the mgmt trouble, cause its host responsibility to ensure their tenant clear the premise on time for their cleaner, and to comms with the mgmt.
you give them assurance you will be out exactly at ur specified time they usually ok 1. like at 10am u say, you alrdy packed everything, ready go checkout liao. you just want to go somewhere for breakfast first. want to go for a morning swim, meeting friend downstairs at noon, etc.
ya another is also can do laundry, and got microwave. n i suppose homestay kettle n fridge safer. since u got washing machine. in hotel u have f up ppl microwaving their soiled socks n undergarments. boiling them in kettle. refrigerating them, power la.
also about learning the right thing? i suppose you also follow the no shoes inside rule?

you also off the aircon when u leave the unit even tho u coming back later?
make the bed, clean up the place?
put everything back as if you were never there? got clean up your own hair from the drain/toilet? sweep/mop the floor for them?
there's a line between doing the right thing and doing someone else's job for them. imo u are disrespecting them by doing their job for them. implying that they are incapable.
how would you feel when ppl come and do your job for u at work?
you paid the cleaning fee, it's their job to clear the trash. to me doing the right thing is enabling them to do the job easier. it's not to needlessly have trash everywhere.
It's bagging or placing your trash neatly so they can just grab and throw.
just like returning tray here. outside of hawker center and food court, or when return station is full at these location, the right thing is placing dishes neatly in the tray and leaving it at your table so cleaner can just clear and wipe the table.
