Pier 91, Seattle for mobility issues

My adult "kids" & I are leaving from Pier 91 on May 20. I've never departed from Seattle before.

I have mobility issues -- can't walk/stand too far or too long. How is Pier 91 to navigate?

I've encountered terminals in other ports that have very long, often zig-zag ramps.

Trying to decide if I need to ask Princess for boarding assistance.

Thanks!

Unless something has changed since 2012 plan on some ramps but usually it's straight on to the ship bridge style. There will be wheelchairs available with people to assist.

The above videos might give an idea about what to expect. Also, this second one is what happens in Seattle when people drink too much coffee. ;)
