As was pointed out, the $72.99 price is already counting the 50% off one when buying two. I have read about some folks being able to buy just one if their cabin mate doesn't or can't drink alcohol. You or your TA have to contact RC about that and I'm guessing they would then charge you $98 per day.
The math is a bit wonky since it's 98 + 49 = 147 ÷ 2 = 73.50 per person. So they are actually "rounding down" by 51 cents.
Whatever, I did put this in my shopping cart & saw that the charge would be $1377.92 with the added 18%. That is some chunk of change! And we still need to budget for cabin gratuities & shore excursions. So yeah, we are really thinking this is just too much for us.
But still hoping to find out the latest individual drink prices specifically on Wonder. Would love to see menu pics showing wine/beer/cocktails/coffee. If anyone knows where that info might be please post.
