Interesting topic. Obviously, there is no right or wrong here. We have not stayed in Aqua, but we have stayed in a Sky Suite, and the Luminae experience is similar to Blu. We have also eaten in Blu as a suite guest. We love the smaller restaurants. Not as crazy. Not as loud. Better service. We are, in essence, assigned a head waiter (all of ours have been men so far) who quickly gets to know us, and provides great service at every meal. He only services a handful of tables at a time. Also, remember that Blu is open for breakfast as well as dinner, and has a great selection. If you opt to spend the money on specialty restaurants instead, which is also a good option, you will be doing the breakfast buffet (or MDR) in the morning. Blu also will have some menu options that are lighter than those offered in the MDR. Aqua has a few other less significant benefits, but Blu would be the primary one for us. Good luck with your move up, if you decide to go that way.
