Hey! Another Boise resident here
We usually don't skip anything, but we also at minimum have 4 days to spend in the parks. There are certain attractions/rides I will only do once though. Astro Orbitor (uncomfortable), Autopia (don't like the exhaust smell), Canoes (hard work!) Oh, I guess we don't do Jumpin Jellyfish anymore, my kids have decided they have outgrown that, and it never did much for me to begin with. I do love to do the Bug's Land rides that a lot of people skip though. Heimlich cracks me up!
Can't wait to finally get back next year after a 5 year absence! So much will be new: all of cars land, Little Mermaid, new star tours, BTMRR update, Mickey and the Magical Map. Very excited!
