BECAUSE HERE'S THE DEAL: Reserve a room at a participating hotel and get a two-for-one dealie at places like the Grammy Museum, the Los Angeles County Museum of Art, the Getty Center, the Petersen Automotive Museum, and The Huntington Library, Art Collections, and Botanical Gardens (which truly will be in top bloom during the promotion's springtime period, so good timing there). You'll also nab 50% off, museum gift shop-style. Yep. That's solid stuff. Can you do it? Headed to LA for a graduation? Mother's Day? Just for the heck? "Just for the heck" is so underrated, by the by. Find your hotel and cultural institution, and get planning before the middle of May blows through.
