Indoors, the estate features 12,000 sq ft of venues including The Sinatra Room–a speakeasy-style space with a bar and the Flower Room, a 1,402 sq. ft glass terrace with 18,000 lbs of hand-blown flowers. Winter teams can book an igloo Think Tank. The hotel’s upcoming restaurant Coa will offer a culinary journey of Spain and Mexico.
