I've walked it quite a few times when staying across the street from Endless Summer at the Sheraton Four Points. It isn't a bad walk, but I think its about 25 minutes. The bus might be a better option if time is a factor for you.
This trip we plan on walking in the am and getting the shuttle/bus back. There are a few crossings, but compared to NYC it was not unlike other places I've walked -with a few caveats: 1) I would not walk with small children as it is an unfamiliar area to them and there is one crossing that would worry me 2) I would not walk in the heat or rain. There is no shade from the sun or coverings at all and 3) I would never walk at night. Accounting for those it was a decent walk and we drank our coffee and ate our very portable breakfast burritos on the way.
