Another negative about hardsided is that in order to fully access the contents, you have to fully lay out the open suitcase, which is difficult to do on a standard hotel luggage rack.
Oh wow, you're right! I didn't even notice that! Talk about confusing!
This reminds me of a poster that used to use "BigRedNole" as their screen name. Every time I saw it, I thought "big red mole".
You'll probably find them to be more similar than different, although cruising on Enchantment after being on newer Carnival ships could be a significant letdown.
I find the food on Carnival to be significantly better than on RC, . The service is great on both.
