Ha! I do want to go there but am not sure it'll be this trip.
We have 2 major constraints: can't do Thanksgiving, and my wife will likely only have 5 vacation days available, maybe 6.
Fall ideas so far are Spain, Italy, Croatia, Greece, somewhere else in Europe (Budapest?), Alaska, maybe Morocco or Georgia (central Asia) -- though I'm still gathering ideas.
The rest of Asia is unlikely, esp. if I go there this spring. Australia/NZ will take too much time. And South America (other than maybe Colombia) is unlikely for other reasons -- namely i would want to see a friend in Paraguay, but wouldn't be able to squeeze in both with time constraints.
Just did Croatia/Montenegro last summer and currently planning Morocco for this spring. Lots of good options!
