I usually buy a bottle of rum and now it's at $125 before gratuity. Make 22 drinks out of it at $5.68 per drink. Cocktails on board go between $10.95 - 13.95 so there is savings there. Cheers at 15 drinks for $59.95 (if you drink all 15) is $3.99. To come out even cost-wise between Cheers and the bottle in the room, one would need to drink a little over 10 drinks a day on the Cheers program. I didn't add in gratuity since it is a constant. Now my head hurts from all the math and I need a cocktail😉
