You have to hit option 3 after dialing that number, and then option 2 for everything above a sky suite. Expect to wait about an hour to reach anyone, and they will only take a message to have your concierge call you, as the odds of your actual concierge answering are very low. Being in a RS, you don't want to book online since the specialty dining is included. There have been lots of changes with the shoreside concierges. I've had 3 different ones in the last month and haven't even cruised yet. If by chance you are on the Solstice or Beyond, I do have the email addresses for both of those concierges and could post them if needed. Once you get hold of them, I've found email is the best way to communicate so everything is documented. Note it does often take them 24-48 hours to respond since some things take time to arrange directly with the ship.
