These comparison threads always end up comparing apples to oranges. The OP was asking about an entire cruise line, but you can't begin to compare Jewel and Pearl (brand new ships) with the old fleet from the 80's. Jewel and Pearl are new ship with incredible decor and ammenities. You can't even begin to compare it to the older NCL fleet, as well as the NCAL fleet out of Hawaii with poor service issues.
I am sailing Pearl in 10 weeks. After 4 disney cruises, I decided to try something else, and I was swayed by:
1. price - got a mini suite with conceirge for less than a cat. 11 on
DCL
2. brand new ship
3. fresh water pool (yeah, so is Disney) but the pool deck looks nicer with
loungers, tiki torches, etc.
4. 11 restaruants
5. Freestlyle dining
6. Newer ammenities that DCL does not yet offer, such as bowling alley, rock climbing wall, full tennis court, casino,
7. MOST OF ALL.... Bliss Lounge
Have you guys seen pictures of this?? Beds in the nightclub!
8. Decor- wild, fun, bright, amazing
9. More adult entertainment
10. outstanding indoor pool/sauna/steamroom in the spa, nicer gym and
fantastic heated loungers overlooking the ocean
Don't get me wrong, I still love DCL.
But as far as trying something new, Jewel and Pearl have outstanding reviews and are not the same as the Hawaiian fleet or the older ships. Thats like comparing the Carnival Sensation to the Carnival Liberty, or RCCL Majesty of the Seas to RCCL Freedom of the Seas.
Have a great cruise, whatever you decide.
