As far as free drinks, when the waiter comes, mostly he asked what drink package we had, and we said ‘none, just Blue Chip Club drinks’; usually he also asked for room number—no cards.
Beware, though, because I had one single drink charged to my acct from Casino Bar, which we never used ourselves, so had to be an ordered drink.
I called Guest Relations, who said they’d call casino.
Charge wasn’t removed, so called next day and was told it was a premium drink (only classic are free).
Since I only order one type of cocktail, I could adamantly say ‘no, I only ordered ____, and it’s on the classic list’, and it was removed.
But, most folks might not be so sure at the end of a week, so beware of what you order. If it’s not a classic drink, they won’t warn you, and you will be charged.
Not sure how they can do that without having you sign something though.
