While I'd agree that Kona is probably the more convenient, shortest time to get there choice, I'm not sure that WC is all that much further away.
To get to Kona you can either take the local monorail (which stops at Contemporary and TTC before getting to the Poly) or take the small resort boat from the MK. To get to WC you take the boat from the MK. I wouldn't expect the transit time to be significantly longer going to WL.
