I totally understand your frustration. We are getting married on 9/12 on the ship and I wanted to plan excursions, for when we are on nassau. However she said the time slots are not filled in until a couple of weeks before the cruise. Well, I made my reservations at Palo for 6pm because they had mentioned the wedding would be between 430pm and 530pm. That is not actually true. The captain decides the time of your wedding. So she might have to change the Palo reservations for me.
My frustrations are the same as yours. All I want is to see is an invoice at least that says I paid for a wedding on the ship.
Plus you can't plan half of the excursions because you won't be back in time to get ready if you have a 430pm ceremony. Another tip is, until she actually starts to work on your wedding, you can't schedule a hair appointment either until, you are closer out to the wedding, however Cathy says she will pick the appropriate time and make sure it is booked.
