We like both DCL (platinum) and RCCL (diamond).Some say RCI is cheaper but for every RCI cruise we have taken, the cost has been extremely close what we pay on DCL....sometimes a little more and sometimes a little less (but nothing noteworthy)
We have sailed on RCCL on itineraries not offered by DCL, such as South America (Rio de Janeiro, Brazil; Buenos Aires, Argentina; Ushuaia, Argentina -- to walk among the penguins; Valparaiso, Chile; Lima, Peru; Puntarenas, Costa Rica) and the Eastern Med (Athens, Greece; Ephesus, Turkey; Cairo, Egypt). So I can't compare those prices with DCL.
But I can compare prices where DCL has sailed.
In 2010, we went on the Disney Magic EBTA and WBTA. For two adults, we paid $1,498 pp including tax for the EB, and $1,665 pp for the WB, both in a Cat. 9 oceanview cabin. We booked the first day, and transferred onboard bookings for the Castaway Club discount. Both times we received the CC OBC, which I recall was $200 per cabin.
For 2011, we booked an EBTA and WBTA with RCCL on Voyager Class ships. They have five ships in this class: Adventure, Explorer, Mariner, Navigator, and Voyager of the Seas.
For two adults, we paid $869 pp including tax for the EB, and $935 pp for the WB. We will have a Cat. E2 balcony cabin on both cruises, and will receive $200 OBC for booking onboard. We are RCCL Crown & Anchor members, booked early, but not on the first day.
If we had booked oceanview cabins on RCCL, the cost would have been around half of our oceanview cabins on DCL.
YMMV.
