Hey there butternut!
Congrats on selling the house(almost) and sorry about the computer. We've missed ya here!
My sister went to hamburg durg the Christmas season a while back and had a great time. Of course, it was her first time in Europe, she wasn't backpacking, and her boyfriend lived there. It will be cold, thats for certain.
For me, any place is worth going if I haven't been there. I don't care what time of year! I'll pack the right clothes and prepare for a great time in a different world and at the same time, I'll expect the unexpected.
Have fun in Mehico(as Voyd would say
)!
