cocktail party

[no nothing about wine]

OK, We are throwing a cocktail party for some friends getting married. The party is at the end of May and although mixed drinks will be popular - we will have some wine drinkers there too! (some of them are wine snobs) so I'd like to get red and white - nothing too heavy - we're in the deep south
whites - light crisp not too dry
red - a little fruity, smooth and easy
any suggestions? Oh - I forgot to mention not too expensive, too. Thanks!
