Alright so two of my friends have this riddle with days/nights involved with staying in certain locations (they are on like a road trip?) and the other friend can guess where they are now. It's kind of hard to explain so I'll just say an exact example with the answer. Can anybody crack the code?

"So I went to France and I stayed there for one night.... Then I went to Luxembourg... Then I went to California for one night, but I loved it so much I stayed there for 4 more nights."

The answer is Colombia....

Any ideas on how to crack the riddle?
