Renting Vizcaya for a weekend evening may cost $10,000 ($7500 for a weeknight), but a properly bacchanalian affair should at least have traces of ancient Rome, if only in the form of a few well-placed Neo-Italian cherubs. Though one can only imagine the grandeur with which James Deering entertained in the early Twenties, parties at Vizcaya -- corporate sponsors and unfortunate cover bands notwithstanding -- transport the reveler to an ethereal Xanadu. When populated by a fashionable and enthusiastic Miami crowd and watered down with icy cocktails, the mansion -- with its view of the bay and ornate courtyards surrounded by labyrinthine gardens -- inspires a sense of mystery, beauty, and fun.
