If you choose not to wear it, you can request an RFID card from the front desk of your resort that you can use for almost all instances that you'd use the Band for (room key, room charging, park entry, FP+, etc).
If you have a stand-alone park ticket that you bought separately, as long as it's linked to your MDE profile that card will also work in place of the Band for everything.
That being said, I wore the Band all week last week and barely noticed it. (Even had a few times I quickly glanced down at my wrist to see if it was still there because it didn't feel like it was)
