OK gym really looks the same except for the paint job. Still a decently equipped gym nevertheless.
Yes, protein shake fridge was locked when I was there. +1 vote for making protein shakes a SPG platinum perk.
Getting to the replacement gym at the Westin was much further afar than I anticipated and I was not a fan of their gym either.
The lounge is definitely worth it. We saved a lot of hassle and money since we did breakfast and late afternoon snacks (easily a full meal) there. Excellent selection, quality, and staff.
