i know this is not what you are looking for, but it really is personal preference. We have been on the Wonder, Fantasy, and Magic. So, I can share my experiences, but what matters to me might not matter to you
1. Dining: I'm not sure if we just got a bad serving team on the Fantasy, but our dining experiences on the wonder and magic were amazing! Super personal and attentive waiters who made us feel like we were their only table.
2. Crowds: We never had trouble finding deck chairs by the pool on either ship- I didn't notice much difference in the crowds at deck parties and in the atriums. They are always crowded- I was surprised that a lot of the activities in the D lounge were never crowded (on any ship) my kids got to be part of almost every game- vs just being part of the audience.
3. Clubs: every club on every ship has been amazing! my kids weren't old enough for the tween/teen clubs when we went on the wonder or fantasy, but they LOVED them on the magic. My kids did miss mid ship detective agency when we went on the magic, but that was really the only thing.
4. Staterooms: i'm not aware of any plumbing problems on the older ships- we stayed on deck 2 on the magic and I think our rooms were wonderful (so was our stateroom host). Thats the other thing- we got to know our staterooms hosts on the older ships and never saw ours on the Fantasy (my kids called him our stateroom ninja) might have just been a coincidence. We have 5 kids, so we have to get connecting rooms. And since we really don't use our rooms except to sleep and change we always get inside rooms. I thought the kids would miss the magic porthole on the magic, but they didn't even mention it's absence.
5. Castaway: just get off the ship first thing. People sleep in- we noticed more people when we sailed the fantasy, but not until around 10:30 or 11
We are planning another cruise- I finally convinced my family to try one! And it's on the Wonder, mostly because the itinerary and we want to see the new changes since we last sailed the Wonder. You may notice some difference in the ships, but No matter which ship you choose- disney knows how to do it! There's a reason we are now planning our 4th cruise, when we swore it would be a once in a lifetime thing!
