Something people never seem to figure is the space ratio for passengers. I think space per passenger on Edge class is probably at least a third more than Oasis class. In other words, you will feel less crowded. This space ratio probably goes up with the quality level of the cruise line (along with fare). We recently were on Regent Seven Seas Splendor and sometimes wondered if we were the only people on the ship. Our next cruise is our second on the Edge where I found that, at certain times of the day, there were areas I had almost to myself.
