Who do you want to give too much information too.
When you apply for casino credit you must give the casino a ton of personal information and though I do have two credit lines, I did give thought about where I applied.
I tend to play fairly large stakes in some corporate places and often (not always) do this unrated so if I get tossed the rest of the corporation is still immediately open to me, I would hate to be spreading like mad and run out of cash on hand and have to ask for marker while playing unrated, so that is one of several reasons that I have no credit line in these corporate joints.
My credit lines are at independent places, where I spread a little less, rathole more, play a little VP, and get nice comps while still playing a winning game.
