Unfortunately, Tie the Knot, the people that Princess contracts out their wedding planning to has thrown us under the bus. When our TA contacted them they said "oh sure, we can get you married that day". When I contacted them AFTER the booking, they said "sorry, no can do". Like three couples suddenly decided to get married on that cruise all at once?
Anyway we've had to shift bookings, flights, hotel reservations, etc and now it's happening June 13th. Same boat, same itinerary, different day.
