Thanks for the posts. I'll check into the suggestions.
As for how long and what, we're probably looking at half a day for the tour, something like 4 hours or so. This is what I did last time and we covered all the quarters, starting at Mount Olive, quite nicely. Might include a bit to eat. It's a quick overview, yes, but that's the point of having a personal tour guide - to share detail as we go, find short-cuts, and take us efficiently though the 'must-see' bits...
Cheers,
