Hello, I'm new to this....

I was hoping to find someone who travels with their children/child. I want to go on a vacation-cruise and found so far--that the Cunard line is the only one with a kennel! Anyone out there know anything different?
Also, who has experience putting the children in cargo when flying?
As I have 2, it's impossible to take them in the plane together,
I need some advice. Can I put them in a wire cage instead of a plastic kennel? I was told that AA would take them when the temp was above 45* and under 82*. I plan to tour Europe with a rental car.
Go to dog shows, flea markets, etc. and relax.
Hotels/restaurants, etc. welcome small well behaved pets there.
I've done this before with a poodle/no problem, but now I have

boys!! (who need girlfriends!!)
