Doug, I can't think of anything much worse than having the flu while in a house full of visitors and on New Years Eve/Day. Smart to check into a motel where it is nice and quiet. Let's hope your malady is short lived. It usually takes me a week to get over a bout of flu (knock on wood) but maybe your system is tougher than mine. Drink lots of fluids.
FWIW, it's 38F and raining here in Portsmouth.
Growing old ain't for sissies!
