Currently (we sailed Dec 9-16 B2B on the Wish), there is no need to pack and has gone back in most aspects to pre-Covid. We exited the ship as late as allowed, completely left the building, and then went through Security again before new cruisers. We spent probably about 30-45 minutes off the ship going through security and waiting in the terminal for clearance to re-board and just took our port arrival form and IDs. We were given the detailed instructions the day before - left in the stateroom. It was really easy and I hope we never have to return to testing prior to re-boarding on a B2B. We were a party of 2 adults, BTW.
