Thank you everyone!! Great advice all around. Cash it will be for the gift. I will bring a casual-businessy outfit or two and do some shopping for a salwar or kurta or two.

I don't have any word yet on where the wedding is or how big, but I do have the impression that the family is quite well-off, and I know this wedding has been "in the works" for at least a couple years. So, it may be quite the party. You can bet I'll have my camera. ^
