Well—thanks again for everyone who posted; it really helped a ton!
Six days wasn't near enough, but we got a lot in.
We took the boat tour to Tracy Arm, well worth it—the captain got us to within spitting distance of the main glacier! We saw several humpbacks, including a pretty close cow and calf. Saw some Dall's porpoises, didn't even know there was such a thing.
We hiked Perseverance trail up to the overlook into Silverbow Basin.
We hiked the short Rainforest Trail on Douglas Island one evening; our rental was on Douglas Island.
We hiked up to Gastineau Peak and the short finger ridge (Gold Ridge) with breathtaking views of Gold and Silverbow Basins (wife and daughter took the tram cutting the elevation gain in half, thinking I should have too

). Saw several goats and a black bear about a mile off (brought my binoculars everywhere).
We toured the ski area; wife is thinking we should go back for a Winter trip
We hiked the West Glacier trail that overlooks Mendenhall Glacier; trail got really tough (there were ropes here and there, but not enough) about three- four miles in so we gave up going to the top of McGinnis (if we go back, I hope to bag that one).
We hiked the Boy Scout trail (after doing Gastineau to let the legs recover); salmon were running and we lost count of the eagles we saw.
Our last day the ladies wanted to shop (and not hike!

). I toured the SeaAlaska native museum and then climbed Mount Juneau- 3500' in 4 miles is no joke. Saw goats up there too. It whetted my appetite to do the loop down the ridge to the head end of Gold Ck and back out.
We ate pizza at Island Pub (twice!!!). Ate halibut tacos at Deckhand Dave's. We ate a ton of Russian dumplings at Pel'meni's. We got several Dungeness crabs and cooked them at the rental. We picked the meat of the ones we didn't eat and then got a large halibut fillet the next night for stuffed halibut.
We packed our raingear religiously, but only donned it once on the boat tour—weather was as close to perfect as you could get.
