A very interesting post. Apparently we are neighbors as we listen to the MK fireworks every night at our house. 🙂
We are significantly older than the OP, and frankly prefer to sail on Royal than DCL. Basically because of the price point and the benefits of suites on Royal. We still love Disney though and have sailed on all five of the ships. Plus we just booked a sailing next summer to see their new private island.
But again, the price point difference is significant. You can get a veranda cabin on RCL for probably 70% of the cost of a similar cabin on DCL, when comparing similar itineraries.
We also enjoy the ability to try the up-charge restaurants on the Oasis class ships when we sail. We do enjoy Palo on the DCL ships as well.
But, we are solid Disney fans and really enjoy our visits to the parks. We also enjoy watching the interaction of the children and the characters both in the parks and on board.
