Hi! The WL concierge was just fine - the staff was very friendly & nice. They don't have a concierge lounge, so their food is on a buffet table along a walkway, and the tables/chairs are kind of spread around. The food was decent, not GF quality, but pretty good. Continental breakfast in the morning with a few pastries, cereal, and fruit salad. The afternoon snacks were a bit heartier, with ribs offered one day. We had some wine one evening, but the cheese selection wasn't terrific. The cordials were pretty good - Bailey's and Amaretto when we were there.
I'd say that if you plan on eating breakfast there, and maybe a snack during the day, it's worth the extra $30-45/night. Plus, it's cool being on the private 7th floor. Your fireworks view is better, if you're on the MK side.
Cheers!
