So I live in an area that cruises are a popular option for many and yes RC seems to win out over Carnival and Disney. I will say it would be RC, Carnival, then Disney if I counted all the cruises people I know have been on. Yet, some people feel they HAVE to do Disney and if they do it when one kid is a certain age they need to repeat it. So there is still people who want to do Disney and frankly Disney has less ships so they are not going to get everyone. I am not in that have to group and will stick with RC Oasis and Icon. I unfortunately have an extremely picky family and if there are no trees on the boat (Central park on Oasis and Icon) my family won't go on the ship.
However, I will say I priced out and Icon cruise and wow, $3 to 4k more than what I paid for Oasis in 2022.
