Here's an example of the difference for hubby and me and we have only done AI at Couples. We can drink their drinks all day and feel fine. I can have one margarita for $7 and hubby a martini at The Parrot and stagger back to my beach chair at Coco. Definitely cheaper for us to do NON AI. Also we eat way too much food in the AI that just isn't necessary (can't help ourselves-no self control) .
