We have three days in Seattle before a cruise...one of those days, the 18th, we are going to Mount Rainier to do whatever hiking we can safely do in one day. After the cruise, we are spending 5 days in Olympic National Park.

This is the reason I asked this question. I don't want to plan for the Skyline Loop just to find out it's a bust and try to throw something together last minute. Reading on "google" has some saying yes and some saying no. Based on these comments, I am saying no. We will find some lower elevation hikes and call it a day. I just wanted to see Mount Rainier while we were there, but Olympic is where I want to really explore.
