We were in an Owners Suite (8506 if I remember correctly) which is a very convenient location. Not that the ship is so big that its a long walk anywhere.
As far as service goes, we had some good interactions and some blah ones too. Some were happy to help. Others seemed to only do the minimum for their job. Rather spotty. We didn't attend any of the shows so I can't comment about those. We did get a Massage and it was good - as good as we've gotten on the Disney ships, but not as good as we got at Aulani. Found it difficult to get a chair around the Solarium pool but that's probably because we are lazy and don't get there early.
We never ate in the main dining room so I can't comment about that. We enjoyed Chops several times. Did Giovanni's Table twice (maybe 3 times) and enjoyed the food, but the meal took way too long. Izumi had good service and food - fun. Windjammer was OK. You'll have no problem finding something to like there. The biggest issue was that our traveling party of 5 (3 different staterooms) needed a larger table and those are harder to find during the busy times.
Our cabin attendant was nice. Didn't actually meet her until day 3 I think, but everything was fine in the cabin.
Getting on/off the ship in the ports was pretty easy. We never tried to be the first ones off so I don't know about crowds then. The security crew was friendly. It was also a nice touch that they had water waiting for us when we returned to the ship. We only tendered in one port, the rest of the ports we were docked.
