I love RCL, but i think that if they build anything bigger than oasis will be getting out of hand. I know that i wouldn't want to go on a ship that huge because i like meeting people and it would be really hard to do on that ship. Also, when you go to an island that is very small it would be way too crowded and would kind of bring down the experience. I think that if RCL is going to build more ships they should build more ships like the Adventure Class because that class of ships is like the perfect size.
Also, the more ships they build it's going to be more expensive to cruise on them because they are using all their money to build the ginormous ships and it costs more to maintain them and build them, and that cost would just be passed onto the consumers.
