Perhaps people could see your side of all of this if you could define what it is you mean when you use the word "abuse". Comments like this naturally cause others to say, (and it happened again in this thread), "I have never seen the abuse of which you speak". But the problem might be that something that you see as "abuse" someone else sees as "legitimate". So the two of you might be seeing the same thing but interpreting them differently. You seem to have a pretty good handle on what Disney considers to be abuse. I am not aware of any published guidelines, but obviously you are part of the inner circle and know what is abusive and what is not. So...
With respect to bottles of wine, how many bottles could one bring on before they are found to be abusing the system? One bottle per day per adult couple? One bottle per day per adult person? However many bottles it takes such that the guest spends no money on wine while on the ship?
With respect to beer, how much was "legitimate personal consumption" and when does it cross the line into "abuse"? Three bottles per adult per day? Six bottles per adult per day? Whatever amount causes one to drink only their beers without buying more from the ship? Whatever amount makes one "choke on your own vomit" drunk?
And with respect to spirits, how much could one bring on board and still be non-abusive, and at what point does one cross the line into abusiveness? What did Disney consider to be the the proper amount, and how much did passengers bring on to get them labeled as "abusers"?
Once we have answers to these questions, then I think we can have an intelligent conversation about personal experiences and whether or not "abuse" was taking place, and whether or not such abuse was witnessed widely by the guests on the ship. If "abuse" means bringing on three bottle of wine or a six-pack of beer, then I think that you are right on the money and abuse was running rampant. But if abuse means that people were bringing on so much alcohol that people were staining the carpets with their vomit on a nightly basis, then I'd have to say, no, I did not see that type of abuse. Until we define "abuse", we cannot have this discussion.
