An update on the ever changing Tourist Card procedures:
Last week I flew into POP and out of STI. In POP I tried to exchange the old green tourist card for the new computer card; just as I had done at the end of December. It seems they are no longer exchanging the cards. No matter how much I complained, I was still required to pay an additional $10US for the new card.
As other posters had noticed, they collected the new cards shortly after they issue them. (Since I was bit sloshed at the time, I can?t tell you exactly when they collected it).
Upon leaving STI, I expected some problems because it seems they didn?t stamp my passport on the way in. As other posters have noted, they didn?t even bother to check my passport for my entry stamp. As a matter of fact, they almost forgot to stamp my passport with an exit stamp.
