It's in the fineprint that it can't be combined with Shareholder benefit..However, this is over and above the pick your perk..so it's being reported by people onboard that you can get this OBC and the drink package while booked on board and then if PYP comes back and is applicable to your sailing, you can drop the drink package you acquired onboard and still pick your two perks..then you could really get all three, OBC, Gratuities and the Drink Package. Of course you have to pay prevailing rates. This came into play starting March 1st.
We're on Solstice in a couple of weeks and will be booking our 2015 med. cruise while onboard.
