ahbitheman I personally would not do this since on Santorini it's all about the outside and the view and not necessarily the room. IMHO for 2 nights the Allure Suite is fine.
I'm a little confused by your post, are you getting married or are you attending a wedding there? If you are getting married then I would think they would have done more for you especially if you are bringing them revenue for other guests rooms and a onsite function. If you are attending then I personally would not be expecting/hoping/planning for more.
