I LOVE Disney, but sail
DCL more for the Disney reputation, than Disney anything else (i.e. characters {hardly even notice them}, etc.).
The ship is extremely well kempt & gorgeous. I've cruised on two other lines prior to Disney & the staterooms are definitely larger, unless you pay for a very large stateroom on another line. The crew is 'Disney-friendly'. To me, it's a lot like how I feel about WDW - comparing a wonderful themepark to a regular amusement park.
I am willing to try another line like RCL - only the newest ships, though - but think I'll miss the special things that are important to ME:
1) Adults-only areas (pool, clubs, beach area, restaurant, etc.)
2) Fresh water pools
3) Rotating to three different restaurants
4) Nominal fee at Palo's - the ONLY restaurant that charges - not
a bunch of them & not $20.00/person
5) Free soda at meals
6) 'Clean' entertainment
7)
Castaway Cay - It is beautiful & private
8) The ship's horn (O.k., THAT is Disney, but I would miss it!)
9) Feeling comfortable & safe with the kid's clubs
10) Wonderful shows/productions
There are other things, too, but those are the main ones. I sat down with a couple that just got off RCL Mariner last weekend & their cruise sounded wonderful & enticing, but when I weighed what's important to me, I realized that I will probably end up liking DCL better in the long run. I would still like to try RCL because it's something different & there will be a different itinerary & shows, but it didn't sound like it fit the bill for what's important to me. Plus, to get a newer ship, you have to sail for longer than the 4-days that we like to do.
Mainly, the biggest draw to trying something else seems to be the initial savings of money, but after I realized that we would have to spend $20.00 per person each time we wanted to try a different (& from what I hear, a MUCH better quality of food than the regular) restaurant on the ship AND that I'd have to pay for my sodas even at meals, I realized that the difference in the $$$ spent would be minimal.
