Thanks for the tip, nmnita for posting it on the Princess thread as well.
We looked into RCI and NCL and found the ship to be very large with over 3000 people on them. We don't like crowds too much and fear that it would overwhelm us. We were drawn to Holland because of the simple and classy ships and supposedly good food.
We are going Nov 8 so it won't be during Thanksgiving. My travel agent tells me that my kids are at an age where they will have fun on any boat and since it is our 1st cruise it will be great for them anywhere so he suggested we choose a ship to cater more to our needs. I know the NCL and RCI have lots of features (skating, flow rider, rock climbing) but I don't think our family would use any of it so it really does not matter. I think our main priorities are a good stateroom, kids club and a good spot to just lay in the sun and do nothing! We just really want to experience cruising and what it's like to be on a ship.
