I mean, it's nice to have an option for a quick programme when you have guests over and actually it's good to do a couple loads in a single day. But yes overnight I don't care, it can take 6 hours and I wouldn't mind.
Time it to finish when you get up and it will release a lot of warm (humid) air to help you warm up your house
It's on a timer anyway because we have cheap electricity from 00:30-04:30, so I just run it alongside all the other appliances within thouse hours(and charge our car too).
