FORT LAUDERDALE, FL—According to guests lined up at the front desk and seated at the nearby hotel bar, the entire Marriott Courtyard lobby was treated to every song in 4-year-old Emma Freeland’s catalogue Wednesday while her parents checked into their room. “I thought she might just sing us ‘The Itsy-Bitsy Spider,’ but no—she segued right into ‘Twinkle, Twinkle, Little Star,’ and then launched into an energetic choreographed rendition of ‘I’m A Little Teapot,’” said business traveler Sean Erskine, explaining how the complimentary show then continued with an extended four-minute rendition of “The Wheels On The Bus” as Freeland’s parents negotiated for an oceanfront room with a pull-out bed.
