The first one would fit with carribean style vacation/honeymoon travelling, I would think. It's very whimsical, and if that's the kind of feeling you're trying to accomplish, then I think you should continue to investigate the first concept the most. Visually, it's the most pleasing to me. The second idea, if further tweaked, could be a decent take on a kind of "Royal" aesthetic, as the shape of the ship resembles a crown. If you could change the windows to jewel shapes, drop the pencil-thin lines, and throw in a nautical detail or two that would give direct reference to "ship, cruise, resort", you'd have a nice concept there as well. Back to the first concept: The height of the steam vents should be more exaggerated. You're going to need more variation in line width however, and you'd want to really continue on with the movement aesthetic. Either that, or completely ditch the lines and create the shapes out of positive / negative space. Take a look at the line width variation of this image. It's an illustration of a GTO that I'm working on at the moment (it's in progress still, I realize the window borders and rims are not complete). I'd think this style of drawing would benefit your logo:

As all designers tend to be, I'm going to be brutally honest and say that the type needs to go back to the sketchbook. I have no intention of insulting your work, but the logotype really strikes me as something that was a 1st attempt on the computer, skimping out on the conceptualization process entirely. I'm very guilty of doing this, myself.
