On my late March sailing there were some staff shortages (mostly bar waiters) and supply shortages, but they seemed to re-supply at Port Canaveral. The staff was pleasant and seemed to be happy to serve. The only issue we had was that it took 3 or 4 attempts before they finally acknowledged and fixed the cabin's lack of hot water.
We sailed at the end of March (8 day Bahamas). We arrived around 11:15 for our 11:00 check-in. No wait to go inside (11:30 check-in line was held outside). Quickly through security (had a D+ "bypass" 🙂 ). Separate check-in line for suites and Pinn, but just a single line for lower tiers. Line moved somewhat slow, but I think we were on the ship shortly after 12 noon.
Yeah, haven't seen a US based ship at 6 PM for a long time. For me, 5:30 is too early, but 6 would be okay. I did do 8 PM late seating for a while, but that become too late for me. I now just schedule MTD everyday at 6:30 or 7.
ETA: I just did a mock booking for June 19th Explorer and dining times are 5:30 and 8.
Same for the Anthem TA (arrived at 12:15 pm).
The only backup I've encountered was Enchantment (Baltimore) in late March. Arrived on time, quickly through security, but then a slow line for check-in (not in Suite or Pinn).
This has been my experience on 7 pre-COVID Grandeur cruises and 1 post-restart Enchantment cruise. I don't recall ever seeing more than 2 people working (or separate lines) at Cafe Lattitudes.
I was "stuck" at 163 points when cruising halted. Now at 309 points. 🙂 Four "solo" cruises (with no solo supplement!) for a total of 31 days (124 points) + 11 days shared cabin (22 points). One more double points cruise in the fall (14 days = 28 points).
