Have you hiked/biked the Hiawatha Trail in north ID?

There’s a lot of info online about the Hiawatha Trail in north Idaho; I’m interested in dopers’s experiences.

The scenery is obviously stunning, but how about the experiences of bike rental, equipment quality and reliability, waiting lines, reliability of the return shuttle, helpfulness of staff, etc.

We’d be driving a long way to get there and will be renting equipment so would like to know what to expect.

Any info/tips appreciated!
