I think it's pretty common to see moose there. I saw one too but was able to finish my round. Kincaid is probably in my top 3-5 courses I have played.
I only played Peters Creek and Kincaid around Anchorage, but would say Peters Creek is worth the time too if you have it after Kincaid. Nice tight technical course in birch forest.
I also played Girdwood which will be on your route down to Seward/Homer (if you're driving). That one can be skipped IMO, but it's in a pretty setting. And the one course in Seward which was a decent 9er. There were a bunch of other courses on the Kenai Peninsula (Seward/Homer) that looked fun, but I didn't get around to playing them.
Other stuff in Seward - Don't miss the Kenai Fjords boat tour, besides the fjords themselves we saw so much wildlife and it was fantastic. My partner and I liked the Alaska Sealife Center too. It felt a little less curated but more connected to nature than some of the other aquariums I have been to, which I appreciated. The Exit Glacier hike in the national park was OK. I wish we had done the Harding Icefield Trail hike there, that one is still on my bucket list but it's a bit tougher of a hike.
Between Anchorage and Seward if driving - We parked and took the train from Girdwood to Spencer Glacier area which was a cool little hike surrounded by mountains and only accessible via the train. Whittier is a fun detour, you have to drive thru a 2.5 mile one-lane tunnel to get there. We didn't really find much to do there but beautiful views. Alaska Wildlife Conservation Center near Girdwood was OK if you want to see land wildlife up close.
You already said Alaska is the best place you've visited so you know it'll be fun no matter what you do.
