Good morning Nanas!!
Steph, we started cruising in May of 2005. This is our 3rd
DCL. We've also done 1 NCL and 6
RCCL in that time (with 3 more RCCLs currently booked.)
We cruise DCL because they treat our daughter like an absolute princess.

We find our fellow cruisers on DCL to be more accepting of the fact that we have a child with us on the cruise. She's very sensitive to reading other people's feelings and she picks up on how some of the cruisers on other lines don't like kids. Not fun... So DCL is something we do periodically for her. But I have to be honest and tell you that we really do enjoy our RCCL cruises. Especially if it's just hubby and me.
To those who are sensitive to smoke, we've actually had much better luck on RCCL. Maybe because many smokers tend to hang out in the casino which I can easily avoid? We're hoping we fare better on this 3rd DCL because our first two were
not good as far as smoking went. On our first we were downwind from heavy smokers on the verandah right next to us. On our second I booked an interior cabin since the verandah was wasted on the first. Every night the interior stateroom reeked of fresh smoke while we were trying to sleep. I don't know where it was coming from because we were surrounded by other interiors.

Yes, I should have said something to the Purser's Desk but it was only for 3 nights so I just bit my tongue. In hindsight I guess that was foolish. I guess my point is that if smoking is an issue DCL is not the guaranteed cure.

Yet, I've never smelled smoke in any of my RCCL cabins nor on the verandahs.

It's all the luck of the draw I guess...
