I have an 18 month old going with us and I was doing a last minute review of our excursions etc. I'm freaking out because he isn't listed on any of the excursions. I thought I remembered that since he is free for them he isn't listed, but now I'm worried that he isn't old enough to go on them. (I can't find where I read that he wouldn't be listed if he is free.) can anyone confirm?
