Okay, 2 credit cards. If the limit is not enough, you can call to increase the temporary limit first. If you go a few days later, you can avoid waiting in line. I remember that I went there on a Friday afternoon. It took more than 2 hours on the road, but it only took 5 or 6 minutes to get there. The staff there were so quick that they had already picked up the piece of paper before they could even think about it. On the way back, holding the piece of paper, I still couldn't believe it.
