Very true.
Before you arrive in Disney, you'll receive a text/email stating your room is ready. If you get that email/text, you just go to your room and bypass the front desk all together. I received mine on the bus actually heading to wilderness lodge.
Some people don't receive those emails for whatever reason. If you don't get one, you do have to stop at the front desk for your room.
However, your magic bands are ready to go once you get inside Disney. No activation needed to use them (charging/tickets/dining.)
