YMMV, but this is what we do...
As Diamond or above, you get 2 additional 50% off beers/wines/soda coupons as well...use those for the beers or cheaper wines first, then use the 10% off coupon for beer each account has. Yeah, you do have to tell bartender..."I want to do this"...so you are paying for beers or cheaper wine, but then use vouchers for more expensive drinks in evening. Seems to work for us, no drink package and our beer expense has been nowhere near the cost of the beverage package for 2. Probably closer to 200 for the 7 night cruise total bar bill. Some nights we were not even using all 5 and stopped and picked up unopened beers for the next day for pool or PDCC, etc.
And now that we made Prime ( drinks when casino is open), we wont ever buy a package again...(again, buy is relative term as getting to Prime was cheaper overall than a single cruise drink package...we were lucky)
