Well, what you make can mostly depend upon what you have, unless you plan on going shopping. Vodka is an incredibly versatile mainstay for mixed drinks. You can go with a screwdriver, sex on the beach, etc. Or you can go the route of a silk panties (1/2 vodka, 1/2 peach schnapps). Great as a shooter--just make sure to have both alcohols chilled in the freezer, or shake it with it and drain into a double shot glass.
EDIT: Take some advise from a sailor who has taken care of many drunks--eat something before you drink, and have some bread or crackers on hand for those that imbibe too much.
