Yes, all resorts have always had the option to do online check in. But not everyone will have the option to skip the front desk
What's changed is it is now available beyond 60 days. Not sure how far out, always available as soon as we book but I don't book a year out or anything, usually just 3, 4 months at most.
Your doing online check in has no bearing on going to the lobby to check in too.
You may get your room number via text, you may not.
You may arrive before they have a chance to send it. You may just not be one of the ones who get it. No way to know before hand.

Totally your choice.
