So, I am checking in today for our first ever cruise. Just want to make sure about a couple of things. I can go and edit my CC information at a later time, right? And, just because I say am I going to do xyz for my post cruise information 73 days out doesn't mean that it's set in stone, correct? Speaking of post cruise information: we are visiting with a couple of families in FL before heading back up to WI. Should I just put in my home address as post cruise info or do I need to do all of the people that we will be with? Just want to make sure I am doing this correctly. Thanks!
