There are 3 butlers. One for each side and the Garden Villa on that side. There is also one that takes care of the courtyard for breakfast and lunch service from Cagneys.
There is one Concierge for the ship plus their assistants. Pick up your cordless phone that you will get to carry arround and they will take care of any request. You should find the concierge in the Star Bar most mornings and at lunch. It is closed to all but VIPs during the day. If you wiss to join the other vips you can go there for breakfast and lunch in Cagney's. It is outstanding.
You can get the same food served in the courtyard or your A3 if you wish
