With Memorial Day pricing that started yesterday, my next 3 cruises are coming in at $66.99, $72.99, $72.99. With the diamond drink perk factored in there is no way I would break even over the length of the cruise at those prices. I would do a little better than breaking even on sea days but on any port day I would definitely end up falling behind by quite a bit.
I'm buying a soda package and buying a 24 pack of water to cover the non alcoholic beverages and will live with paying $7.50 for a few beers or ciders each day. I'll reserve the diamond drinks for the $13 cocktails and when I total up the bill at the end of the cruise I'm sure I'll be ahead of having bought the package. I'm thinking that this is going to be the most affordable way to go.
