Key seating is only a benefit if you go early enough to use it before it opens for everyone. On EN, D+, Pinn and Key reserved show seating is at the back of the theater. We sit there sometimes, but it really isn't the best seating for anything you want to see clearly on stage. We've never found any benefit of the Key as we already get 48 hours each free internet and suite boarding since we always book JS. Boarding day lunch, we normally book a specialty (usually Chops) but for our upcoming b2b Jewel cruise in Oct, none of them appear to be open on Day 1. We'll play it by ear and do a walkup. We have used the WJ in the past on boarding day after cabins open as the crowds disperse then, but now with most opening at 2 pm, that is even more limiting.
