Well I will have be the voice of support for the Grand Floridian as it is our favorite Disney resort over all others, including our
DVC favorites.
We have stayed there many times and never had anything other than a magical experience. This is not to say you can't have a great time at other locations, as you can, but I certainly would not rule out the Grand Floridian if you are able to get it. It is a very special place.
I think you would be pleased with either Grand Floridian concierge or Polynesian concierge, I can not recommend either Beach Club or Yacht Club concierge, we were not impressed with the lounge area, the staff or the views from the lounge, or the food offerings for the cost. We love the Yacht Club, but will not do concierge there again. I would give the Beach Club concierge a slight approval, but if you want concierge in the Epcot area, definitely try the BW Inn,
I love my DVC but if I was wanting concierge opinions about Disney resorts, a DVC forum is not where I would gather all my info. If you go back to the Resorts forum and ask about concierge versus DVC you will get many different opinions. It is simply a matter of what one is used to and likes and some have experienced both as we have but many haven't.
So for concierge my choices would be: Grand Floridian, Polynesian, BW Inn, and Beach Club in that order.
Good luck with your decision.
