Everyone will be staying at the house.
I selected and paid for the material months ago. The way the contractor drug their feet at getting to the point of even getting the materials here is what makes me hesitant as to whether it will be done on time. I've not worked with them before so I just don't know. Those tv shows I know are a misconception that things can be done in days, if only.
It would be really nice to have it done but the more I think about it, the more I am thinking realistically, the movers are booking weeks out. How will I know the contractors will definitely be done to have the movers put things back, let alone get the little things like lamps, make the beds, and other things put in place. (?)!

I don't want to be stuck with a disaster for their vacation having to put the family to work, helping to put things back.
You bring up a really good point, I don't want to be exhausted when they are here. I have a hard enough time keeping up with my nephew even when rested. I wish I could bottle up that energy that he has in a pill and take it, then it would get done in no time; if I could do that, I probably could even get the floors done and the move all by myself, little stinker.
It makes me sad to think that he won't see it in person. Perhaps I can take pics or video it for him when it is done instead.
