When are you going, and do you have little children?
We've gone in mid December, so it is not a terribly busy time. We've never bothered with stratgizing, as we found there really never was much of a wait. We just went out to the bus stop at the main building when ever we felt like leaving and waited - never more than about 10 minutes. The only problem is lots of time we ended up standing - but my youngest was 8 the first time and 10 the second time, so it wasn't really a big deal. However, if you are going in a really busy season, or with very small children, it might make it more necessary to think about strategies.
