One difference I noticed at several casinos in Caribbean (Aruba/St Marten) is that the dealer will deal out the players hands as well as dealing himself ONLY ONE CARD UP. After all players have either stayed good or busted, the dealer will then deal himself his remaining cards. So instead of being dealt 2 cards in the rotation with everyone else (one up and one down like the states) the dealer gets only one up with everyone else.
I have also come across casinos in Caribbean where the dealer can hit on a soft 17. I believe that gives the house a bigger edge ........
