And having spent nearly the entire day there on Thursday, I can tell you that was worth the entire trip alone (well, for me anyway).
I bought a spare battery and 1G CF card for the "old" S50 Canon just for this occasion. Good thing, too. I've twice exhausted the original battery while only half way through some of the sight-seeing trips.
Been taking quite a few night shots (mostly without the flash) and I can wait to see how things turn out on the big monitor.
we're out of here tomorrow and I haven't even touched the slot machines, or any of the tables. Might get to that today..... maybe.
