I love this hotel. Plan on multiple showers....the BEST hotel shower ever.
I barely remember the lounge...but I do remember not being impressed and probably not worth an upgrade if it costs money (IMO)...I would spend the extra money enjoying a drink or appetizers in the bar area downstairs. Being a Platinum ( I was then as well) they gave us drink coupons for the bar as well as lounge access. Once we checked out the lounge we made a beeline for the bar downstairs.
