I'm headed to Mumbai for work later this year, and as long as I'm on the other side of the world I was thinking of tacking on some vacation time and going somewhere else.

I'm having trouble finding ideas of places to go though. I was just plugging different locations into the 'multi-city' finder, and pretty much any locations that I tried were showing as unavailable. Am I doing this wrong? How can I figure out what options I have for locations that won't break the bank? Any suggestions would be much appreciated.
