Some people hate overplanning trips. I'm personally amazed that there are so many detailed and expert planners that post about it here.
We usually wake up in the morning, decide what park we want to go to, and call Dining to see if we can get a PS at one of our favorite restaurants around lunchtime. We're usually, but not always successful, and when we can't get into our 1st choice of restaurant, we've always been able to book a 2nd or 3rd choice...so no big deal.
As far as the honeymoon couple, ask them nicely if they have a "special" restaurant in mind or if you could help them with any PSs for their trip. If the decline, don't push the issue, they may prefer a more relaxed style of vacation.
