Hi were traveling on our first Windstar cruise, Windstar Legend, and they have a pre cruise land tour in Istanbul for 3 nights /4 days (2 1/2 full days of sightseeing) in a 5 Star hotel. I would love to hear from those that have been on a pre cruise land tour with Windstar before (extra points if it was the Istanbul one) to help us determine if its worth the extra $3k in terms of value and enjoyability. TIA.
