Becky, we have stayed concierge at WL and liked it very much. The only thing we didn't care for were the enclosed room balconies. You have to stand up to be able to see out. Since we enjoy sitting on our balcony and relaxing this was a problem for us.
Just got back from 11 days at WL, Club Level (Concierge). We have stayed club level at WL many times, however after this trip, I will not waste my money again. Perhaps at another resort, but not at WL.
