We have also sailed
DCL 4X and
RCCL 5X. We strongly prefer DCL, for big production show entertainment, free movie theater with 1st run movies, better food in MDR, better buffet, and that Disney feeling. But, RCCL is a good product. I have also had inefficient and "sorry about that" staff on RCCL, but usually find "we'll try our best to fix it" staff on DCL. When we say we are going on DCL, the kids (now young teens) are thrilled, when we say RCCL, they are "OK, but where does the ship go?" Also, the teen 12+ areas are not staff during the day, so there is no hang out place like on DCL. I also thought that they did not do a good job with the outdoor Movie screen--played sports/poker most days. We like a set schedule with some moves during the day/evening. The 2 movies show on a 5 day cruise were during dinner 1 night and at 10pm another night. But, there was a 3D movie in the production theater on a sea day.
I find there is a big difference in pricing for holidays, such as Christmas/Easter and in August in the Carib, when most other cruises are much less $$. Such as next Easter:
$3k for 8 day Carib with 4 port stops on RCCL bigger ship (not the newer ones) for family of 4 in OV cabin. The cabin will be smaller and offer no privacy (bunk beds over twin beds) and no split bath.
$3500 Wonder 5 days OV to CC and Cozumel. Better cabin layout, better bathroom.
$8K for Fantasy--balcony (all that is available), but when I priced it a while back, an OV for 4 was about $6K. That is a Starwars cruise, so I would add a premium to that if I had any big fans, and might have splurged for $6K (double the price of RCCL).
If we REALLY wanted DCL, would have considered the 5 day Wonder, but the kids voted that 4 port days trumped DCL, so it's RCCL for us, with somewhat lower expectations. We will really miss the movie theater and the fun dining experience. The "extras" for us will be at least 2-3 nights of specialty dining--adds $100 per night for a family of 4 and soda, if we wanted. We don't really have many other extras on board--maybe a few frozen drinks, souvenirs, Johnny Rockets for 1 lunch or dinner for the kids.
For those considering RCCL, I give it a solid B, with lack of Movie theater C, unstaffed teen areas during the day C, and meh food some nights in MDR B-, and lower quality buffet B-, outdoor screen B-, smaller room C, balanced against the A+ price, climbing wall A, skating rink/ice show A, flowrider A, burgers for lunch B (instead of buffet), Johnny Rockets A, some good entertainment shows A, more ports/more days A. If you have active kids/teens who would use a lot of the unique sports options and you were on a Voyager, Freedom or + ship, then I would say it's definitely a B+.
