First off, thanks for all the replies to my first question. HUGE help! Thanks to all who replied

I was wondering some questions about the Carnival ship, Sensation, is it a nice ship? I've read how some older ships show their age, is this one of them? Second, with room placement. I am debating on where to stay on the ship. Should I go for a cheaper interior room or is Ocean view worth it? What about decks (Riviera, Upper ect.) is the money I would pay for the higher decks worth it? I don't want to be stuck in the cellar next to the engines or anything but I also don't want to pay more just to stay higher up when the lower decks are just fine. Any posts from people who have been on the ship and the decks they would recommend would be great! Thanks again.
Oh, one other thing, how soon (or how late) should I book the trip? I'm looking for late Aug-early Sept. right now. Should I be booking that now or can I wait until early summer (like april-may)? Thanks.
