The Sea Club, a five-level, 30,000-square-foot conference center built next door to the recently refurbished 313-room Le Meridien Beach Plaza Hotel in Monte Carlo, opened in October with a ceremony featuring Prince Rainier. This seems only appropriate, since the Principality of Monaco financed the construction of the property. The twelve meeting rooms (of which three are divisible into two rooms and one is divisible into three, for a total of 18 meeting spaces) reflect a royal touch, from the undulating ceilings meant to echo the Mediterranean's swells to the glass door handles the color of the sea. The Principality spent $22.5 million to create this dreamlike space by the sea, and every dollar shows. Most striking is the ground-level ballroom, which has glass panels that slide back to provide a view of the Mediterranean.
