It’s hard to tell which seat is the best one in the house aboard Premier’s new 290 Grand Entertainer. Is it the über-plush captain’s chair at the Royal Command View helm, raised six inches off the sole for an expansive view of the water? Is it the bow sofas backed with Premier’s exclusive Flexsteel technology, which acts like shock absorbers in your seat? Or is it from one of the three cushioned stools nestled up to the rear-island bar? Depending on your desire at the time, it could be any one.
