I'll be visiting with my wife the second week of December. And by looking at the temps.....54-57 seems to be the trending high and the low seems to be trending at 34-37. Wondering what to wear? I'd assume that most of the time we'd be just walking from the casino to the car, then driving to whatever indoor mall, etc. Not sure we'd actually be out in the open much other than maybe watching the fountains at the Bellagio and maybe walking across the pedestrian bridges. Being from Hawaii, we only have two temperatures..........hot and cold! :evillaugh So anything that is below 74 is considered actually really cold for us. What do you folks wear when you're out and about? Do you layer, etc.?
