Todd - glad to see that your post made it over to this board.
I will suggest to you again that you seek out a travel agent, sit down with them- tell them what you are looking for, wants and don't wants, likes and dislikes, and let them make suggestions tailored to your needs.
Each cruise line has its only personality shall we say, and they gear towards a certain type of cruiser.
Examples: Royal Caribbean - very family oriented, lots to do on board, day and night especially on the larger vessels. Great teen & kids clubs
Holland American - more of the traditional old style of cruising. Not as active day or night as some of the other lines.
Carnival - middle of the road, mass market line - lots to do day and night,very good kids activities, very good quality Las Vegas type shows, lots of families with small childern seem to gravitate to Carnival- the decor is a bit gaudy for my tastes - too Las Vegasy but that might appeal to someone else.
Princess - very nice line, more of a resort hotel feel to Princess ships, good service, lots to do day and night. Very good kids programs.
Celebrity - put this one in the middle between Princess and Holland American.
This is just an overview and my opinion
