I forget the category we had booked on a verandah on the Magic in May. I know it wasn't the bigger one. We upgraded at the port to a 1-bdrm concierge. I realize on the Magic it's not with the cool-factor that's on the newer ships since there's not a concierge lounge. We paid $1200 to upgrade. Worth it? Yeah. It was fun. Not something we'd ever book ahead of time. I wasn't going to go for it but it was my hubby's 40th bday cruise and he wanted to do it so we did. We enjoyed the priority boarding and the welcome reception. Having a concierge assigned to us was nice. She took care of little things we would've had to do like go get the extra Wave phone (which we never were charged additional for), booking a tasting, make sure our shipped box arrived, etc. All sorts of little surprises were left for us during the stay...even arcade cards for our boys to go play with. It was sweet. We really enjoyed it so no regrets.
When you walk in the terminal there's a looooong desk to the left where everyone is being checked-in. You'll have to get that done first. Then, the supervisor's desk will be all the way down at the farthest end of the long desk you were just checked-in at. It'll be all the way at the end closest to the ship, away from where the terminal entrance is. There's a separate line down there.
One of my favorite perks that I wish we had taken advantage of was that concierge guests can order from the main dining rooms' menus and have it delivered to their stateroom. As much as we keep spending on dress clothes for our sons who outgrow stuff so dang fast nowadays, I'd rather spend the money on concierge level and eat in our stateroom a night or two vs. dressing up and being on a schedule. Would be all the same food we love without having to spend time dressing up, etc. We could just relaaaaax...
**edit**
Forgot to mention the standing room service order for the mornings. During our welcome meeting with our concierge onboard the ship (in a nice lounge with free cocktails included) we set up a standing order for coffee & milk at 8:30 every morning. Every morning without fail we received a call at 8:15 confirming we were present for the delivery then at 8:30 the tray arrived. I got so spoiled! When I returned home the first morning getting up, walking down the stairs, and making my own coffee was brutal! Seriously. I was fighting back the tears! LOL!
