I’ve done a 5 tire rotation on most of my vehicles over the last ~30 years (well all that have a full size spare and don’t have different f/r sizes).
I do my rotations and summer/winter tire swaps myself. It’s super easy, only have one wheel off at a time. And if you have a tire failure then the spare has even wear and then until you are due a new set just do a 4 tire rotation. I’ve always done a reward cross as all my street (track cars don’t count) have been AWD.
As for doing it your self, probably a 45 min job the first time and easily <30 after that. It is super easy, with one teen helping me I can do all 4 of our cars in ~1 hour with just: a floor Jack, electric impact driver, appropriate size socket x2, torque wrench, hockey pucks, and a breaker bar.
