I booked WL concierge this past April. We are checking in there on Sunday and I've just booked standard, but hoping to be upgraded! The cost of concierge there was about $150 extra...not worth it to me, but I wanted to experience it. Not being heavy eaters, and as we tend to hang around the resort more than some, it pays to have food available most of the time for us. But the cost of that food is exorbitant, IMO!
Edited to add that $150 is per night...
