Yay Yoomoo, congratulations move day mate!
I know the feeling of relief. I was a little worried, after reading on here, that one of the chain might pull out! But thankfully no one did.
We are using a packing and moving company - I was determined not to move myself this time, and the packing is a bonus. An even bigger bonus is that they have agreed to unpack to cupboard too, I will be home that day so I can get them to put things where I want them, etc.
DH, DD, and I have not celebrated yet - we have not even told DD yet, as I am now on my way back home from a work trip on the continent. So looking forward to it.
How are you celebrating the exchange? Glass bottle of wine?
Knitted, I am sorry. Will taking a step away from here for a few day help? This chain is helpful but it can also be quite intense sometimes. 
Fx for exchange tomorrow Frescoed.
Pussin could one of your chain move out for a week to allow the completion on the 7th, if you offer to help with the cost? That way you get what you want, and the other in the chain can complete on the new build?
Lubey, I hope they come with exchange before xmas. Fx
