Paul, with your Solstice comparison, did you compare "quality" or just quantity? I still think Regent has higher quality, greater flexibility (special orders and requests), and a more relaxed environment than would a suite customer on Solstice.
As for drinks, I guess I come from a part of the population that likes to drink on cruises. When you add in wine price to pre dinner cocktails and after dinner drinks you easily get to four drinks in your comparison without even counting cold drinks by the pool or wine with lunch. Arlene doesn't drink much but she probably goes through a half dozen cans of diet coke per day; that adds up too.
