You've done just about everything for that special event -- booked a venue, hired a band or DJ, arranged for exotic flowers. But somehow you just can't shake the feeling that you've overlooked some detail. Ice Occasions (2800 SW Fourth Ave., Fort Lauderdale, 9547670607) knows what it is. You've forgotten to add the coup de grâce of party details: ice sculptures. Want two swans kissing to complement an engagement party? A luge for chilled vodka at a 21st birthday fete? A replica of your own restaurant for an opening? From private to corporate, stock to custom, Ice Occasions' designs will send the proverbial chills down your spine.
