Since there is no Disney bus service from resort to resort you need to be at either Epcot or the Disney Studios to easily get to the boardwalk area. From Epcot you simply exit at the International Gateway, near the United Kingdom, and it's about a 10 minute walk to Spoodles. You can also take the Friendship boat, but the walk is faster.
From the Studios you can also walk to the boardwalk area. This walk is around 15-20 minutes. The same Friendship boats run between the two parks stopping at the Swan/Dolphin, Boardwalk and Beach/Yacht Clubs. From the Studios you can take the boat which will be to your left as you exit the park. The boat ride takes about as long as walking..... but it's easier on the feet!
