I did that in Cuba 15 years ago -- as US passport holder I was
NOT supposed to be there atall !
They had a smooth little thing going on : if you had the obligatory $20 in your passport , they would stamp
a piece of paper
instead of stamping the passport . : worked like a charm .
: come in from Europe , pay the dosh , and fly to Mex . Then get home . Had great times
!! X
