I've been on 3 cruises post-restart
Bahamas - No special lines for anyone, but since volume was so low it was no big deal
Galveston - Enforced check-in times (sort of), there was a suite lane to actually check in and a "first in first out" seating area for suites in order to actually board the ship in the order you checked in prior to gen pop boarding
Vancouver - Complete fustercluck. Times not enforced and while there was a suite check-in lane it didn't matter since the seating area was one big pool of people, then a mass swarm to board once the ship opened for boarding.
