We just went on our first cruise and I decided to skip it. I was worried that my dd would see fe everywhere and feel left out, but that was not the case. We only saw 2 the entire time we were on the ship and they never had anything in them when we walked by. My dd didn't even notice. We did a 3 day cruise so there really wouldn't have been much time to be doing it. If we do a longer cruise, I'll think about it, but I don't feel like we missed out on anything by not doing it.
