where should i go?

i have one more project to go! unfortunately, i have already been starting to dream about christmas break and on vacation mode! i get 1.5 months off! whoopee! so my dilemma is:
where should i go?
i'm already hitting the warmer parts of the country: oahu this week! :) LA from the 28th-31st. yay, kiddies!
i dunno where to go in january. my choices are anywhere northwest airlines will take me to.
that leads me to the other part of the country where i know ppls: NYC, d.c., chicago, and MN. the only drawback is that i don't want to freeze my fanny off like last year. do i dare make this midwest to east coast trek? OR i can stay at home and heckle ppls while they are at work. mUwahhaa! too bad i don't know anyone in the southern states. anyone up for a vacation? :P
