open sided? not sure what that means... outdoor with a roof overhead? that theme is as intangible as Saratoga Springs Resort Style... no one really knows what they are trying to do...
The original pavilions in Central park with their late Victorian design and Eastlake aesthetic would be a good place to start... Abd yes there are some fountains and gazebos here and there, they just don't come together in any meaningful way...Maybe the sprawling nature of the property... maybe there just aren't enough things to make a statement...
Of all things though, if the Lobby building, restaurant, and main feature pool were more heavily themed, it could carry the rest of the resort beautifully... Get rid of that corporate country club look and make it feel more period appropriate and special...
