Were you (or for multi-stayers are you generally) happy with the hotel/stay?
Yes!

Which room did you book and which upgrade did you receive?Booked King Main building and upgraded to an Exec Suite, Historic Tower (4100)

How are the rooms?As Gmax previously posted, this series of rooms (3900-4200) are one per floor, and require a second elevator ride to reach. The room was a full suite, with two full bathrooms, a formal dining area, flat screen TV, sofabed couch, and a hallway leading to the bedroom. The bedroom was so small there was barely enough room to get out of the side of the bed. However, the two windows gave an obstructed view (building facade) of the south and east, including the lake. Considering the overall charm, the small room was rather fun.

Welcome gift: 3 pieces of fruit, 1 L Evian, 6 truffles

How is the exec. lounge?N/A - there is none.

What was good and what was bad?
Good:
I was very pleased with the upgrade and the courtesy from all the staff. The location was great for Xmas shopping. The concierge gave some excellent restaurant recommendations, including one for breakfast (West Egg, right around the corner).

This property has a great swimming pool and a decent workout area. It is $12/day but waived for RA's. The hotel in itself has a lot of history and charm.

Bad:
Can't think of anything related to the hotel. As previously mentioned, it was foggy with an obstructed view. Also, I was really disappointed by the slow service on the "L" It takes a Blue/Red transfer from ORD. Even the train seemed plagued by congestion, with frequent slowing. It took well over an hour to reach the hotel from the airport. Again, this was no fault of the hotel.

Value for $ or Priority Club Points? Would you return?Absolutely! The favorable rates along with the strong RA benefits make this property a winner. Although no one ever "recognized me" as an RA, etc., the service spoke for itself.
