We are booked on Spirit in November also a 14 days cruise and had the same question. We sent an e-mail to Carnival Guest Relations and received a list via e-mail of the drink prices. On an earlier post someone suggested purchasing drink coupon before the trip. I believe 4 coupons were $20.00. We have not yet been able to find out from Carnival what can we purchase with one coupon. Beer prices run from $3.25 to $5.75, wine by the glass $4.50 to $6.50 and by the bottle $21.00 to $29.00. The list also included mixed drinks, cognas & brandies. If you find any more info on the coupons please post. Hope this helps!!
