The Olafur Eliasson's East River waterfall was switched on this morning. And what did the decidedly midrange Buckingham Hotel do? They announced a silly $75,000 "weekend waterfalls getaway," complete with visits to the (free) waterfalls and a side trip to Niagara Falls. How glam! At least glammer than their $169-a-night leap year promotion a couple of months ago. [NYDN]
