Well we just got back and it is about a 50/50 split as to what side has a better view. Most of the ports were commercial docks so there wasn't really much to see anyways. We were also on the even number side cabins but had an inside room. We were on the lido deck and it could be pretty noisy. That was a major downside, the boat also had a strange vibration that i don't remember feeling on my past cruise. BUT!! It was an awesome cruise and we had sooooo much fun.
A little advice tho, prebook something to do with carnival when you get to St. Lucia. We didn't and we totally missed out on the island because the locals were very pushy and rude. I didn't feel safe at all at that port.
