I guess I misspoke a bit. Boardwalk view is what I meant. So BWV and GV cost the same, just request whichever I would prefer?
If you booked a Standard Room, your room will be a view of anything BUT Crescent Lake/water.
If you booked a Water View Room, your room will be located on(top) of the Boardwalk, overlooking Crescent Lake.
If you booked a Club Level Room, your room will have access to the Inn Keepers Club. These rooms will either have a view of the Courtyard or Crescent Lake. There is no way to guarantee a "Water View" while booking this category, and therefore, as a previous poster mentioned, per request only.
Unless...
You book a Deluxe, Club Level Room. These rooms offer additional space and guarantee a view of Crescent Lake. Some are located on the same floor as the Inn Keepers Club, some on the floor below.
If your wife has her heart set on a water view... the most cost effective way to ensure the view would to simply book the "Water View" room category. The price to upgrade to Club Level isn't that "much" more... but understand you risk losing your water view.
If you don't mind splurging to ensure you have access to the Club Level Lounge and a Water View, consider the Deluxe, Club Level... just understand that your room MAY not be on the same floor as the lounge itself, which can be an inconvenience to some.
