All great advice Cherries! I even got some good pointers! I've been doing NSD for over 20 years in various places. I think this will be my 2nd one here (maybe 3rd...)
My advice is to avoid overwhelming yourself. If outside your scrap room things stay on your mind and you couldn't finish them before you start, LET IT GO! It will still be there at the end of the weekend!!!
By posting in the forum on challenges or games or whatever is the best way to get "sprinkles" and it could put you in a different Cherry category! (Not really worth anything but bragging rights!)
Take a deep breath and look around at the scenery outside for a few minutes every day. It will help refresh your mind.
LET YOUR FAMILY KNOW YOU'RE NOT AVAILABLE!!!!!!! I even have to make sure my husband knows because he'll bug me too! And it's just us.

Put a sign on your door and lock the door if necessary!!!

This is YOUR play time!!! Treat it like it's precious because it IS! They can handle it for a couple of days!!!
And like all the other Cherries said HAVE FUN!!!!!!!
I'm really looking forward to it! I'm prepared to even turn my phone and/or computer off for a bit if people keep messaging or calling me.
