Um, I would choose WL Club level, BUT I would try really hard to do Poly Garden Club level instead. I am a concierge spoiled brat (I admit it), so I would always choose concierge over not, but I hesitate to return to WL (although I LOVE it so) due to the transportation problems I encountered there last Feb. It was really bad...bad enough to make me never stay there again, the thought of which makes me very, very sad. I hope they fix it.
If you can tolerate LONG bus rides with lots of sharing w/other resorts, a LONG wait for the boats, and an INSANELY long travel time from resort to resort if you need to do that, then pick the WL. Otherwise, choose the Poly. The time and aggravation you save on transportation will be worth the loss of the concierge.
