Funny you mention getting sea sick, I was just thinking that. It's been a long time since I've been on open ocean, but the 2 times I did, I puked both times.
I went to Doc Warner's camp in 1996 near Juneau and the water is broken up with so many islands, that there wasn't any swell at all, it was more like fishing on a big lake except obviously there is a lot of tide. I think his camp approach is pretty cool; the 1st day, someone will accompany you on one of their boats (if you want) to show you how to fish for salmon or halibut and then the rest of the trip you can fish for as much or as little as you want on your own. We never did land any of the huge halibut, I think the biggest in our group was around 100 lb, but most were probably 40-60, but still fun and delicious. Not sure if he still does this, but a few days we set out crab pots, too. For us land locked folks, there's nothing like eating fresh halibut, salmon and crab right out of the ocean. Doc's isn't the place if you're seeking solitude, but rather loosely populated.
Another trip in 2006, I didn't get to fish, but was building a cabin for a client on the Ugashik river on the south end of Bristol bay. It's crazy how expensive the logistics get when you're doing construction 120 miles from the nearest road. There are no trips to the store for anything and you better have 2 of everything that's important. This is a fly in area and based on how much was spent on that cabin, I bet the fishing is fantastic and you'll have plenty of solitude if you want that. If you do the fly/drop in anywhere in AK, don't forget your check book!
