My fellow posters are correct, for access into the stadium, they are already activated. The reason for going on the Dolfin "activation" site is to allow the season tix holder to "assign" the card to a person, who then if they have their own Fin Club membership, then any merchandise and food/drink they buy can be credited to that person and then earn reward points. If you have been on the Fin Club site, you accumulate these reward points and then can redeem them for various types of items/services they offer. Anyway, I hope this makes sense as I had to speak to a few folks at the Dolphins before a got an explanation that seemed to be logical. This is my 31st year as a season tix holder, its been a long drought, I know, but I am hoping, yet again, that we will have a magical year in 2013....................GO Fins!
