arsavoy.........I don't really have any advice in regard to an inside cabin. I've always book a balcony cabin or suite. On the Conquest in May, we had a Cat. 11 suite. Next year we just book a regular balcony cabin since we got a great deal from CruiseQuick. As far as which deck........in my opinion, it doesn't matter. The cabins in a particular category will all be the same regardless of what deck you are on. You will love the Conquest. But just a word of warning......if you tend to be cold natured like I am........parts of the ship are really cold sometimes. We eat all meals at the buffet (we quit going to the dining room years ago) and there were times when it was so cold in there, that I would have to go back to the cabin and get a sweater. There were a couple times that the casino was cold enough to hang meat in! :lol But even with having to deal with chattering teeth, I still love the Conquest. That was my second cruise aboard her and like I said......I'm book on her again in 2010.
