I just want to add a respectful counterview to this opinion, because I see it a lot and disagree.
If Disney is in your budget, you love
DCL, and the Med itinerary looks appealing, I think it can be worth the extra money. We did the Italy/Greek itinerary last year and easily felt we got our moneys worth and had more than enough time to enjoy the ship. I didn't feel like we used the ship much less than we do on a Caribbean cruise, even with longer port days. First, there are two full sea days for many itineraries, where you want to be on a ship you enjoy, which gives you a great opportunity to unwind in the middle of an otherwise busy trip. Next, you spend every breakfast, dinner and evening on the ship, which is a large percentage of your waking hours. Let's say you get up at 7, off the ship around 8, back on by 5 (the latest for most ports) and in bed by 10. That's still almost half of your day on the ship. We had plenty of time in the evenings to go to dinner, then a show, and often even adult entertainment after that. This was our first time on the Magic and I left feeling like I did everything I wanted on the ship and spent lots of time on her. I remember being worried that we would feel like we wasted money, but we
loved that trip and were really glad we went with DCL for it.
Admitedly, other lines do tend to have later port times than DCL. But that wouldn't really appeal to us, because we find we are exhausted after an early morning start and coming back around dinner time, or a bit earlier, is perfect for us.
I personally wouldn't sail DCL in the Med right now, because I think they made their itineraries worse, but if they go back to last year's itineraries, or better, I would highly recommend them for DCL fans. It was nearly a perfect trip for us. That said, we are branching out to Celebrity in the Med next year, because we want to see if DCL is worth the premium to us now that we are tiring of the evening shows and menus (and sometimes too many wild kids - yes, we are getting old!). We have a hunch we can get most of what we like about cruising with Celebrity or another line at a much better price. We will see.
