Eastern Mediterranean first time cruiser

My wife and I are celebrating our tenth anniversary with our first ever Mediterranean cruise next spring/summer. The Sea Cloud (on Lindblad/NG) looks amazing, though if I'm reading the prices right, considerably more expensive than other comparable cruises. Are we on track if this is what we're looking for? Here are our concerns/criteria:

1. want to be a small ship

2. want a lecturer on board to help us with context/history

3. want to concentrate on Turkey and Greece, possibly Dalmatian coast

4. looking for 10-16 days

5. cannot leave until May 24 but don't want to be there in hottest season, so are thinking month of June is our window

What sort of experience have others had on the Sea Cloud? Any tips for cabin choice? Any other tips?

Sea Cloud is expensive . . . we've not sailed on her but last year we sailed on Corinthian which does many Dalmatian area cruises. We thought the whole thing was pretty flawless. It's chartered by Travel Dynamics.
