We are staring to get serious about researching excursions, etc. for our "Ancient Adriatic Treasures" cruise next spring. The description of "Day 1" of the Istanbul extension reads: "Disembark your ship for a visit to the striking Blue Mosque, stepping inside to admire its ornate interior. Continue to the Underground Cistern to glimpse its illuminated interior, a space supported by 336 columns. Then, set out on a scenic cruise along the Bosphorus Strait while savoring a tasty Turkish-style lunch. Back on land, visit the Grand Bazaar for a presentation on Turkish carpets, as well as time to browse the many stalls. The rest of the day is yours to explore at your leisure." Can someone here interpret this Viking Speak for us? What does "stepping inside" mean? What does "glimpse its illuminated interior" mean? What is a presentation? Is this all a thinly veiled "keep them busy" type waste of time between disembarkation and hotel check-in? Please help.
