We love The Wave, and for quality of food, we go with it over CP. BUUUUUUTTTTT....
You lose quite a bit of time if you're planning on coming back to MK after your meal. It's a 10 minute walk at a fairly brisk pace....longer on very tired feet. Plus, the time on getting back through security and the gate. Monorail can be shorter to The Wave if you catch one waiting at the station, but will be longer on the return trip.
Although many are fans of leaving a park and coming back after your meal, we're just not. We plan our resort meals for arrival days and early park closing days. Your mileage may vary.
Just another thing to think about.
