Just got back (yesterday), RCCL out of New Orleans. Ultimate drink package = Cocktails, wine, beer, and of course soda and water for free-Just show your Sea Pass card with the sticker and off you go. No signing anything. Went to the same two or three bars, and didn't even have to show the card after the third day- They knew us.
Also, just booked an Alaska Cruise on NCL Jewel for August 2015. Special now is a free Ultimate Drink package with the booking of Oceanview or Balcony cabin. Package is for both of us. Also includes a $50.00 onboard credit. If you book an inside cabin, no drink package but you do get a $25.00 onboard credit.
