This was probably the most beautiful part of my trip to Italy. I strongly, strongly, strongly urge you to hike the entire trail. You might be tired by the end, but it is an absolutely amazing hike and you will have some breathtaking views. I stopped to eat in Vernazza as well, just straight off the dock, they had tables lined up outside. Very good seafood. If you don't have a hotel already, GET ONE. I didn't have one, and ended up going from door to door in towns looking for a vacancy. Didn't find one and had to train it back to La Spezia and sleep in a roach motel .
