First, I'll admit that Lark was my first female who wasn't spayed before her first heat so I've had just one round. However, it really wasn't too bad. I think you expect bleeding to last 4 weeks and you need to keep her away from intact males during that entire time, even if the bleeding seems to have ended. The bleeding fluctuates in amount and color. I read some females keep themselves pretty clean but I had Lark wear a diaper and put regular human panty liners inside and changed those out. She didn't mess with her lovely little pants and I think during that whole time only 2-3 little drops of blood actually got onto the floor. She was in her crate overnight with no diaper. I only allowed her to go out into our backyard and went out with her. We didn't have any issue with male "suitors", there are no loose dogs running around our neighborhood and our older guy is neutered. I didn't really notice any behavior changes on her part. It was less difficult than I'd feared.
If your parents' home has hard floors in an area where she can be confined and you take a crate, it may be manageable, as long as there's an OK place to take her outside. The pants can be found at places like Petco or Petsmart. Finding someone to watch her so close to Thanksgiving may be a stretch. I know our kennel has been booked for several weeks now.
