I know most of you answer the “How will I celebrate Elvis’s birthday” question months in advance, but booking airfare to Graceland is expensive this time of year and the impersonators at the Flamingo are off until the end of the month. How about an impromptu road trip to Palm Springs to see the king’s Honeymoon Hideaway instead? Celebrate at the house this Saturday with rockabilly star Glen Glenn, a tour of the modernist retreat and its secret passageway, a Priscilla lookalike, and a “special surprise” from the belly dancer that appeared in Elvis’s 1968 Comeback Special?! Whew! No question, this is the place to rock-a-hula this weekend. Viva Palm Springs.
