"The Empire State Building offers a "Happily Ever Empire" proposal package, which includes a dedicated corner on the 86th Floor Observatory for proposals, a celebratory bottle of Champagne, a private guided tour through the building's exhibits, and access to the 102nd Floor Observatory for photos. The package costs from $1,000 per couple and must be booked at least 24 hours in advance, with only three engagement slots available each day." - Travel + Leisure Editors
