Obviously it varies here and there. But generally there are a variety of mini-bottles of spirits, gin, vodka, a couple types of rum, scotch, whiskey, bourbon, tequila. There are usually a couple splits of wine (Sutter Home if I recall). A couple bottles of cordials, might have been Tia Maria and Sambuca, but I'm not positive. There are also a few cans of assorted beers. Definitely Bud, and an import, maybe Heineken.
There are also a variety of sodas, all Coke products, Coke, 7-Up, Diet Coke, and I think Ginger Ale. There are a few cans of juice, including orange and V-8. Some parmalat milk.
There are cookies, assorted nuts, candy (Gummi Bears or Jelly Bellies and some sort of chocolate like a Mars bar or M&M's.)
Bottled water of both the fizzy and non-fizzy variety.
Those individual bowls of a couple types of cereal. A trail mix type of thing or raisins.
If applicable the souvenier refillable mugs for your resort. A disposable camera.
Depending on the resort there may or may not be more. The BC seems to have more assortment than the GF. I don't even recall a minibar in my concierge room at the GF, BWI or AKL...maybe they do'nt have them in the concierge rooms?
Remember, anything you take out you are not only charged the applicable charge, but also an 18% service charge, plus tax. So that $2 soda is actually going to cost you about $2.50!
