I liked Homer as a side trip from Anchorage, and the drive can be interesting, but frustrating as well, depending on when you do it (day of week, time of day) for traffic on the Seward/Sterling Hwy. I can see how the spit might make some think "touristy" but we didn't. We watched the planes land on the water, on our way out to the municipal campground. We were actually passed by a motorized hang glider, while driving to the end of the road. I laughed when I saw the local package store, aka "The Rum Locker". Great name, very amusing "pirates and swashbucklers" themed name. It even had a Starbucks in the local Safeway, which was a nice touch. The views from the little welcome center rest area at the top of the hill as you approach the town, are spectacular, as they are from just about every other elevated viewpoint along East End Road.
My greatest regret and error, was to completely miss the tunnel to Whittier when we were right there. Didn't know about it until we got home.
Alaska is definitely worth the drive/sail/flight. We plan on returning soon.
