I am by no means an expert on this, but I'll tell you how I made my decision. I think it depends on you.
We were on the Spirit, I think, in 2004??? We were in our early 30s at the time and both recently transferred to new jobs, so we didn't want to spend alot of $. We also figured we wouldn't be in our rooms that much, which is why we opted for the inside to begin. Going to the Carrib. I expect the same will probably be true for you as well, if not on shore, you'll probably be on deck.
We chose the 6th floor, to put us somewhere in the middle of the decks to avoid the sea sickness. We also chose mid-ship for the same reason. (You may want to do this also if this is UR 1st cruise and you're not sure how you'll react.) I don't remember anything being far away - maybe one of the didning rooms was a little far off??? (I think we had to go up, then over, then back down again, or something like that - don't quote me though...) I do remember one of the bars being fairly easy to get to - I don't quite remember the trips back to the room afterwards ; )
We were concerned that we'd be right under one of the main decks and we were afraid of overhead noise, but it didn't seem to bother us, but then again, we were on an Alaskan cruise with many older folks. I do remember though, that on the last day, when all the cabin doors were open, that the layouts for rooms *035 & *535 (6035, 6535, 5035, etc.) we're quite bigger and we wish we had chosen one of those rooms. Since it's the Carrib, things may be a bit noisier - maybe deck 5 then?
There are many others on here that can offer better insight than I can, but I hope that helps.
I am pretty sure we were on Deck eight, mid forward, and it was just fine for us. This was an out side cabin, I saw the insides on this floor and they were very nice. What was handy about this floor was how the main decks were just under us, or a quick elevator up to pool etc, although we rarely did that, and just took the stairs and tried to work off the last nights dinner!

I am excited we just booked two cruises in October out of New York. The first week we go on the Crown to Bermuda. Then we get off in New York and board the Jewel for Canada / New England. This is our 8th cruise this year.It is great to be retired.
