Pre-Registring - DVC resorts

[heybets30]

i'm coming up to the 60-day mark away from our Aulani stay. I know I can pre-register 60 days out.

What does pre-registering entail? And do I need any info to complete it? They have our names & kids ages already ... Just curious what the online process entails (and getting excited! 56 days away from HI!). Thanks!
