My wife and I will be visiting Vienna (Sept. 5-13, 2013) staying at the Renaissance Wien Hotel and Rome (Sept. 14-22, 2013) staying at the Courtyard Rome Central Park as part of a European trip to celebrate our 50th. Anniversary. Has anyone stayed at these locations and can provide information regarding up-grades ( I am a Platinum Member), location, transportation etc.
I stayed at the Rome Central Park property and loved it. The rooms are large and modern with great air-conditioning, but as you may have read elsewhere, the location is not ideal. Although it's a short walk to the commuter train station, the schedule is sporadic during the day and weekend. The staff was fantastic as was the breakfast.
As far as an upgrade is concerned, we did get a room with a view overlooking the Vatican, but that's about it.
I stayed at the Vienna Marriott and loved it too, but haven't been to the Wien property.
