We do not resurface rotors unless there are grooves or other uneven wear on the rotors, or there is other problems such as runout, wear (lifetime pads = wear on rotors instead), or corrosion.
If rotors do exhibit these issues, we rarely re-surface them. New rotors now are so inexpensive, it's only about $10/rotor more for us to put on new ones, vs resurfacing once you factor in labor time. I generally offer the re-surfacing option to customers of there is enough material to be re-serurfaced. They usually opt for new anyways. About the only time we fire up the turning machine is when we a have a rare car and new rotors and drums are not available anymore.
Even on our MDTs (F650s), it turns out new rotors are pretty cheap.
But if you decide to get them turned, it should not be an overnight ordeal. It's about an hour turnaround time for a pair. Just enough time to swap the pads and do an oil change during the wait.
If happen to be coming by Corvallis on your travels, I'll make you a good deal on a brake job
