Unless you are very tolerant of waiting in line, I recommend you either get the express pass or RIP tour. After my wife and I went to our first HHN, we both decided that the Express Pass was part of the cost of going, and if we couldn't afford to get tix with express, then we couldn't afford to go. I don't mind walking a lot, but I can't stand waiting in long, slow moving lines. Obviously many people don't mind waiting in line, because there's a lot of them doing it.
