Ditto. I would temper expectations because if you rate a regular X show a 4 out of 10, than an E-Class show will only raise that a point or two at the most. Every post-cruise survey I praise the crew, rate the food quality low and comment they should have a nightly comedian in addition to the 7pm and 9pm show
While at a show, when sitting in the back, something we noticed is that roughly 10% of the audience is have their phones out. If it's a GOOD show (usually a powerful singer), folks will be recording the performance with their phone. If it's a bad show, they'll be doing something on their phones, not watching the show
