Plats get lounge; probably river view
My experience as a plat at County Hall, and other plats who have posted here: you automatically get access to the concierge lounge and are extremely likely to be upgraded to a river view. Please note that there are river views and there are river views. You want the one that includes a view of Parliament and Big Ben. This view will probably also include the London Eye (gigantic ferris wheel). I'm told certain river views give you the London Eye but not Big Ben and Parliament. This would be nice, but not nearly as nice. I'm guessing that as a plat, you didn't need to spend the money. Nevertheless, the view is spectacular, and the lounge breakfast and afternoon snacks very nice. Enjoy.
