last year, last week of august, my entire family upgraded when we arrived at WL. They charged us $50 per day to upgrade which is amazing. We have stayed concierge before, but didnt book it because we had 4 rooms between the entire family. They were the best! I had an incident where my hp digital camera broke the day we arrived. They gave us hp's info from the website and helped us package my camera up and received the fed ex new camera and had it in our room as soon as it arrived. They just cannot do enough for you. They try to get you ressies if you decide you want to do something you didnt previously book, they have made spa appts. for me etc. They were wonderful during hurricane frances, very accomodating and actually gave us complimentary park passes for the days we missed due to the park being closed. They really try to accomodate any request. So this year, we are going the same week and have already booked concierge. I would recommend upgrading if possible.
