Welcome back!!
We did a NCL cruise in June that included Greece and Turkey - so thankful to get to see those areas. Weren't they intriguing?
Would you believe that on that 12-night NCL with you guys, we only saw entertainment one night? That "read up on the next day's port" took priority each night.

Right now I am trying to figure out pre-cruise for WBTA... and am intrigued with Prague - Vienna - Salzburg (or Budapest). Hoping to incorporate some mission work for a couple days in Prague if we do go that route.
Ditto everyone who shared about looking at other cruise lines.
DCL was out of our budget (and timeframe) for Greece/Turkey but I think we were able to book NCL for the four of us for less than half the DCL cost. For as little as we were on the ship, we had zero regrets doing that.
Welcome aboard!!
