Robb, don't worry about pleasing a couple of kids who get demanding. Updates are nice, but I don't expect them every day while you are still *on* the vacation! Enjoy yourselves and have fun, and if that means waiting until you get home to post some updates, so be it. The fanboys will survive.
I do find it a bit strange though that no one else that's currently on the trip is contributing much to this thread. I thought people would jump on now and then and post bits about their days. Guess they are too worn out to worry about the internet!
