Hmm, I'll do my best. There are many experts on these boards, so please feel free to add your expertise!
apulk:
Our oldest is only 10 so I don't have any experiences with the teen programs, sorry. We also don't have much experience with the clubs (just can't seem to fit it all in on the 3-day) - someone else will definitely have the answers for you, though!
10:30 is a bit early, but you can still get there, check in (you'll get your "Key to the World" card which states your dining rotation at this time) and hang out until it's time to board. They gave us our Navigator (daily listing of what's going on) at check in, so that should keep you busy while you wait. When you're able to board they'll direct you to one of the lunch buffets and you'll get a chance to relax and regroup before running off for your reservations. The Navigator will tell you where and when reservations are being taken. If it's a "must-do" try to get there a bit early to ensure that you'll get the time/day that you really want. Make sure to pack swimsuits and shorts in your carry-on so that you can hit the pool upon boarding.
If it was up to me, I think I'd skip either Parrot Cay or Tritons for dinner. Parrot Cay just seemed to be the one spot where I felt the choices weren't as appealing to our family. The food was good, but Tritons and Animator's Palette seemed to have more choices that I liked (of course, it's all subjective, isn't it?). Triton's is lovely but it's most like Palo and you may not want to have two "formal"-type dinners in one night. I would not want to miss Animator's Palette especially with my family. I have a feeling you'd get a different answer to anyone you ask on this one!
PiperG: Actually, I was quite surprised to find a nice, hot breakfast at Topsiders. They had scrambled eggs, bacon and sausage. Bagels, fresh fruit, assorted pastries, cereal, yogurt, etc. Just about everything except the omelet station. We've always done the sit down breakfast on the last day and feel a bit rushed through it. This was very nice and relaxed. I wouldn't hesitate to do this again.
By the way, has anyone else ever noticed how the donuts onboard taste a lot like Krispy Kreme donuts? I wonder if they're made on the ship or brought in? They're yummy!
