That's right! They come to see you, not the house. Even though we think they will notice it is very true they wont. Every year I think my house is a mess but when everyone comes they tell me how nice the house is. I decorate and I guess all they see is the decorations and us. Imagine that? Those that notice shouldn't come here because they are here to see us.
This past week or two has been very hectic. Mom is moving in with us and I had to get the decs up, finish my homemade gifts, get her room set up, find a place for the closet stuff and try to wrap before we take off 600 miles to get her. I did a little each day and I did it, I just have wrapping to finish! The cleaning can come later because in all reality, it will get messy with everyone coming in and out. I'll just wait until they leave. Of course the bathrooms will be cleaned and a touch up here and there but no deep cleaning until it's over.
So, try to enjoy and get done what is absolute to make things go smooth. Clean after they leave.
