It's pretty darn close. And Disney made it amazing when we did it in '07. The music onboard, the characters' costumes for different ports, the food, the extra shows. I know I already said this, but it was hands-down the best vacation I've ever been on.
I did a trip report for this cruise, which I posted on another forum. But that forum went belly-up and I didn't have the foresight to save a copy of it. But I made a Google map of our trip, showing our ports and some pictures from excursions. If that might be interesting to you, you can find it here:

(Hmmmm, the map doesn't seem to be displaying when I click on the link. I'll try to figure it out.)
This was also true for us on our most recent cruise. We dropped our bags outside the Port Canaveral terminal, and then upgraded to a balcony stateroom when we got inside. Our bags came to us with no problem, and no delay, as far as I could tell. They used a very high-tech method for re-routing our bags: Somebody used a pen to cross out the old cabin number and wrote the new number on the luggage tag.
