I agree with PP, if you're already spending time at a park (or DS) before dinner, a POR bus from any park or the boat from DS will be fine.
If you're going to POR from a resort and have to transfer at a park - I've had 4 stays at POFQ and found myself using Epcot a lot as my "bus transfer" park. It just seemed easy and convenient.
It's been a few years, but I've eaten twice at Boatwright's and enjoyed it.
