Ship to ship, theres no comparison. However room to room, the rooms are almost the same. The sq footage with balcony was off by like 2 or 4 square feet. The locations I used are almost the same. Same deck. Same size. Both balcony. Both same side. The location might be off a little bit as the Oasis Elevator shafts are different then Fantasy. Oasis room that I used was a little bit further aft midships then the Fantasy room. When I looked at RCLs site, trying to find a 7 day to do a side by side, Oasis is the only RCL ship in PC that showed up. There was 8 6-8 day cruises for the month of Sept in 2018. 5 in Ft Lauderdale and 3 in PC. The 3 in PC are all Oasis. Harmony and Allure are the other 5 in Ftl.
Basically what I tried to do was to find a similar RCL ship, out of the same port, with a similar itinerary, with a similar sized room. Unfortunately, Oasis is it.
Looking at the ship specs for the different
RCCL classes, the closest that RCCL has to the Dream class is the Voyager class. There slightly smaller. About 6000 tons lighter, 100 feet smaller,Freedom class is 20000 tons heavier and they are longer and bigger. Plus trying to find a comparable itin on the Voyager is problematic at best. There is no Voyager 7 days in the carib at that time. Med, yes.Pacific Yes. Not the carib.
Using Liberty, which is Freedom class, out of Galveston doing a 7 night western, same time frame, 4200. But its a different itin and a different port. Room size is off by 10 sq feet, Libertys is smaller, the next size balcony on Liberty would be over by 20 or so sq feet.
