I liked what you wrote about the Garden villa, I guess it's possible to have a look there if one or both aren't booked. I'm interesting in the Courtyard area too and I guess that it shouldn't be a problem to arrange with the concierge to visit that either.
The last few cruises I took we were in the courtyard. The good news for you they held a cocktail party in the courtyard for all the penthouse passengers one evening so you sould get to see it. For me it ment having to get out of the hot tub early after returning from port so they could set up for the party :evil:
