Eliminating even 1 park (EPCOT) by staying at BWV is well worth it for us. Then again we really spend a lot of time at EPCOT and often walk back for breaks at BWV or BCV. We also do a lot of dining there, so even if we have been to another park during the day-we very well may walk over for an ADR in 15 minutes from our room-where we would leave about an hour before from SSR. Even for DHS we know for a fact how long it will take to get there if we walk, and since we usually have a BW View-one of us will watch the boats from the balcony and let us know when the boat is coming (or just left). As for MK-we usually go during busy times of the year so I can't say for sure always, but we get on and it goes directly to MK (it may have made stops before that), and on the way home, it always stops first at S/D so we just get off and walk over the bridge. AK we only do once and its never been much of a wait for it. Like I said, we hop around a lot, grab FP's for later that day, have ADR's, have our favorites so BWV and BCV give us the best opportunities to minimize waisted time, others may very well simply take a bus to EPCOT (or any park), stay there all day then take the bus back to whatever resort-nothing wrong with that.
