I've cruised twice on Carnival - not on your ship - but I'm pretty sure most of the rooms are the same size - be prepared - the rooms are VERY small - but the good news is, you get used to it!!! It takes a while, but you get used to being in a smaller space - and the bathrooms are the best part - they have good counter space and are a decent size (for a cabin on a boat!!!!)
I cruised on the Triumph and the Entertainment was EXCELLENT - just try to make it to the shows that seem more interesting to you - I enjoyed the magic show the best on our ship...you may want to check that out if they have one. Have fun!!
