This annual promotion's big newbie this year is the welcome return of an ice rink to the Inner Harbor (it opened Nov. 21 and runs through Jan. 19, in McKeldin Plaza). But when you've finished your triple lutzes, there's much more to explore. Photos with Santa run now through Dec. 24, the Christmas Village (see art-market sidebar) is open now through Dec. 24, and the Holly Jolly tour (running today through Dec 25, launching from the Pier 5 Hotel), takes you through brightly decorated Baltimore neighborhoods. And that's just scratching the surface. For a full list of events, go to waterfrontpartnership.org.
