This thread was started in
January 2014, but since I just returned from 3 consecutive Radiance of the Seas cruises in Hawaii and Alaska - I'll add my 2 cents!
BACKGROUND
I have been on 15
Royal Caribbean cruises on 11 different ships. I haven't sailed on anything larger than a Voyager-class ship, such as Explorer of the Seas - which currently sails round-trip Alaska cruises from Seattle. I prefer RCI's smaller and older Radiance-class ships, as I generally cruise for the itinerary and not for the ship as a destination.
I have also sailed on 6 Disney cruises on all 4 ships. There's a lot of "Wow" on the Dream and Fantasy, but I also like the Magic and Wonder. I'm really looking forward to my April 2018 Panama Canal cruise on the Wonder.
The remainder of my cruises were on Princess (5), Celebrity (4), and Holland America (HAL - 4). I enjoyed all of them, and would choose any again for the right itinerary and price.
SERVICE
Only Disney can give you the Disney-ness of "Disney service." Having said that, some of my best dinner servers have been on both RCI and Disney, and the worst dinner servers were on 1
Disney cruise.
NICKEL AND DIMING
The only charges on my last Royal cruise were the daily gratuities of $13.50 pp. I don't drink alcohol/soda/coffee, didn't eat at upcharge restaurants, didn't go to the spa, and resisted buying any merchandise onboard. Whereas on Disney - I usually go to Palo once each for brunch and dinner, and Disney merchandise is harder for me to resist!
CHILDREN'S ACTIVITIES
I don't cruise with kids, so I can't comment about the clubs on either line. My preference is to cruise with fewer kids, so longer cruises during the school year on other cruise lines result in seeing nary a minor!
CABINS
I usually book inside cabins. Disney's are larger than those of most other cruise lines, but I don't like Disney's new beds that can't be separated into twins. The split bathrooms on
DCL are handy for families, but I found them to be more of a nuisance for just two people. Example: Get up in the morning to pee in one bathroom, then switch to the other bathroom to take a shower!
ADULT ENTERTAINMENT
Disney's production shows are among my favorite, and having lots of films to choose from in the movie theater is great. I like RCI's production shows, too, and RCI tends to have a lot more "adult" activities going on. However, most don't interest me, as I rarely stay awake past 10 or 11!
PRIVATE ISLANDS
As beaches go,
Castaway Cay is very nice. However, I'm not a big beach fan, so I stay there only until I've eaten the BBQ lunch, then return to the ship. My only RCI cruise that visited a private island was Coco Cay in the Bahamas. Unfortunately, it was too windy to tender, so we missed it. Castaway Cay has a dock, but ships occasionally can't stop there either due to high winds.
ALASKA
I am sensitive to the motion of the ocean, so I take Meclizine - the main ingredient in Bonine. If the seas are rough, you'll feel it even on larger cruise ships.
I have cruised to Alaska 6 times: twice on Princess (1 northbound from Vancouver plus an independent land trip, and 1 round trip from Seattle ); twice on HAL (1 northbound from Vancouver plus an independent land trip, and 1 14-night round trip from Seattle); and my recent back-to-back one-way RCI cruises on Radiance of the Seas.
I think the itinerary is the most important factor when choosing an Alaska cruise. Sailing from Vancouver (whether one way or round trip) gives you a smoother ride and more scenic sailing than a round-trip cruise from Seattle. I don't like the trend to ever larger ships sailing in Alaska, as it overwhelms the small port towns - and most of those larger ships sail from Seattle.
Disney has a decent round-trip itinerary from Vancouver. I used to poo-poo it for sailing to Tracy Arm, rather than to Hubbard Glacier or Glacier Bay. (DCL doesn't have permits for Glacier Bay, but neither does RCI or Celebrity.) However, Tracy Arm is a beautiful fjord, and Disney tends to allot more time to sailing it than other cruise lines do. For those who want a Disney cruise experience in Alaska and are willing to pay Disney's high price tag - it's a reasonable choice.
