Here's an idea that might be really fun. Find out what they're wearing, or have some sort of picture of them. Show the description or the picture to Art, and tell him their names.
Then when they come in, Art can give them a big smile and say "welcome, Mrs. Johnson, your daughter's waiting for you in that room right over there!" they'll feel like the most important people in the world.
And just in case you don't know - Art is the official greeter at the Beach Club - an absolutely charming man decked out in a nautical outfit who greets with a warm smile and salutes everyone who passes through the lobby.
Just one disclaimer - Art isn't there 24/7, so you may have to have a little luck on your side for this to work.
