Sedona,

I was just there several weeks ago, by land. Don't know what the Diamond's schedule is, or where it stand in the cruise schedule, so what you do may depend on how active you are, what time of day the stop is, and whether you are "ruined out". Mycaenae and Epidavros are both amazing archaeological sites, so if you are into that sort of thing, don't hesitate to go.

If you go privately, go as early as possible in the day. Can't remember when your trip is, but it is HOT there, and if it's August, it will be hotter still. Get the site as early as possible and plan to be out of there by 10 or 11 if you can.

If on the other hand, you just feel like wandering around a town by yourselves, this is the place. It is a very nice little town, very pretty, and there are also lots of jewellery shops if you are interested in shopping for gold. There may be guides who can do a walking tour with you as well.

If you decide to wander, I'll describe my favourite sidewalk cafe!

Oh, by the way, it's "Nafplion", although the Greeks don't pronounce the final "n".
