Your stay experience will a draw of the luck
I have had a great stay, many average stays, and a really bad stay. Because this is a mid to low end airport hotel, you never know who will be staying on any particular night which makes the experience extremely incosistent. You also risk, as I found, overbooking by the hotel, and if you end up being a late checking you will end up in a filthy closet, err.....I mean a not so nice room (with smoke smell despite assurances that this is a non-smoking hotel). If there is a rowdy party at the hotel, forget getting the staff to quiet them down, be prepared to stay up with the noise.
On the plus, the club is nice, although I am not sure why you would ever pay for club access since anybody can freely walk in and I am sure do given that its always overcrowded and there are no doors to keep people out. Another thing I noticed about the club is that hotel employees constantly come in to eat from the spread there, which seems odd given that guests are in the lounge.
The workout room has new equipment which is a great if you are a workout person.
They also have reserved SPG parking near the front, which is a really nice touch that few other SPG properties have.
All in all, its hard to predict what kind of experience you will have, hopefully it will be a good one.
