I booked a five night award stay for mid-April at this hotel and took the option to upgrade to a jr. suite for an additional 2,500 per night. As a Platinum, I would expect to get access to the lounge. From a past stay, the most valuable part of this for me was access to a PC to check emails as well as evening soft drinks (bottled water). We like going to cafes for coffee and croissants so the breakfast is pretty much worthless to us regardless of the spread.
Can I request (with valid reason) an upgrade to a larger suite at checkin, or is a jr. suite the best I can get?
Also, is there a particular floor or room number series that I should try to get to obtain the largest jr. suite with the best views of the Tuileries?
