The Grand Floridian offers a similar service ... see below, from Deb Wills' web site.

Private Dining Experience
Our Romantic Packages...For guests seeking that special dining experience, our Romance Packages are the perfect answer. The Romance Packages are carefully selected menus served in the privacy of your own suite, on board our yacht, the Grand I, or one of our float boats or in one of many secluded and romantic venues around the hotel.
We also offer the option of serving items from the menus from any of our restaurants or have our Chefs customize a menu, tailored to your specific wishes. The meal is served butler-style, presenting each course separately. Our Private Dining managers will gladly assist in creating the perfect evening for you.
Pricing depends upon the individual options selected.
