I think if you put it out of plain sight, like a drawer, you should be fine.  I too have never had anything taken from my room.

If you are sailing on an Oasis class ship, the Solarium has a nice buffet for lunch and it is pretty quiet.

I would have too say the Vatican in Rome, Florence, Venice and Istanbul(Hagia Sofia and the Blue Mosque).

I am with you, except I share one suitcase with myb2 teenage son's.  The wife and all her crap is in the larger suitcase.

My kids were is same room, right above guest services, and it was very quiet at night.  We were right across hall in an ocean balcony.  

I know someone YouTube said she always asked for a plate of French fries with here dinner.

As far as onboard experience goes, My family considers food first.  RC has a fair dinner menu in the MDR, although the quality could be a bit better.  Their buffet is wonderful in terms of selection, quality and they change things up daily (not all things). And they have very good specialty restaurants.  Carnival was much worse, especially at the buffet - it was always the same stuff.  Disney, on the other hand was much better in the MDR.  But for 50% more for the cruise is it worth It?  Now that my boys are teens - I would say no. Celebrity and Princess are supposed to have better food, but the extra cost to cruise again begs the question - is it worth It?
 
As far as entertainment and activities to do while on the ship, I think RC has all the others beat.  There is too much to do in fact.  On the quantum class and oasis class, you could literally split yourself into 4 to do stuff all over the ship.
 
I think the storeroom attendants are helpful and kind no matter who you cruise with.  I know the average storeroom is a bit bigger on Disney, but that is because most people sail with their kids in the same room.
 
As for the bars and lounges, the are pretty much the same on any cruise line.  But I do want to try the bar on Allure that goes from the promenade to central park.
 

They are fantastic and I do ask for them now and then.

We booked both of our cruises this year while on our cruise in December...We loved that we could book 2 cruises for a reduced deposit AND got a little bit more OBC.

I would do it onboard for 2 reasons: to pay the reduced deposit and you normally get an onboard credit when you book as well, plus any other sale RC has at that time.  The will ask you for a travel agents name, if you like, as well at time of booking.

You get 15 punch holes and 1 gets punched for every small or medium size, 2 get punched for every large size.  You also get a bit of a discount verses pay for them at the time you order, about 25%.

On the other hand, if Mexico were to prevent anyone with a US passport from entering their country, then it would affect land, Air and sea passengers. As retaliation.
