schedule ahead

Since I'm moving out this month, the owner of the house has started showing the place. Problem is, she tried to schedule these appointments with only like 2 hours advanced notice, and sometimes less. Most days, this wouldn't be an issue, but she keeps picking dates that I already scheduled people to be over. It has been a bigger uptick of that since I have been trying to take advantage of the house as much as possible. Also, it means I can stay home and take care of stuff. The good thing is, that at least I have been given notice and could ask for her appointments to reschedule when I need to, and to be aware and out of the house when it does work out. At least most of the time. Who schedules things at 1am without letting you know?!?!
