I stayed there last month and didn't get anything special in terms of upgrade. I think they gave me a larger room than I booked but it wasn't that great. And that weekend, the hotel was very empty so I don't know why I didn't get a suite or a better lake view.
However, the amentity and chocolates was nice. Bed was pretty hard. Bathroom was nice. Next time, I may choose to stay a little closer into town as I didn't think the hotel was that special.
