We disembarked on Saturday. To follow up on any special benefits for the two-bedroom suite, we didn't notice anything different from the usual Club Balcony suite. In our cabin, we did receive a welcome letter from a concierge providing his extension and invitation to contact him for reservations (restaurants, shows, activities, spa, etc.). We had already booked what we wanted pre-cruise.
You "should" receive priority boarding. This was the absolute worst embarkation we have ever experienced. People started lining up when they called for special assistance. Once the special assistance went through, the mob started moving forward. I was separated from my husband and son. I finally got to the front of the line to be next for boarding, when they decided to send this line to another entrance and had everyone turn around. I ended up at the end of the line. It was crazy. I didn't get to The Local to meet my family until an hour after they'd arrived there.
As for priority luggage tags, the luggage was lined up in the hallways and not delivered to the rooms. We happened upon two of our suitcases and then scouted our third one in an adjacent hallway.
The cabins are opened by floor. We were on deck 11. Our cabins weren't available until 3:00.
The disembarkation was the quickest I've had on NCL (which isn't saying a lot). We had priority luggage tags delivered to our room allowing us to leave the ship any time between 7:45 and 10:00. I don't know if that is a perk for the 2 BR suite or not. Others included with the priority tags were platinum and up and priority.
As for the cabin, I personally missed the balcony, but the space was perfect for us. Hope this helps.
Bon Voyage!
