Hello! DAS is only good for 60 days**** You will be required to re register. Please note, you may or may not be approved even having just been approved 60 days prior!
Yes, as a local AP holder I simply find a blue umbrella guest assistance location inside of one of the parks every 60 days and ask to renew my DAS. So far it has been quick and easy and without issue. The CMs have always been very pleasant and understanding.
