Most of us don't wear them but many people do. Just personal preference.
What is your alternative? Wallet or something else?
Yes, it acts as your on-board 'credit card' as well as your room key. I got my kids a lanyard but they ended up not using it because they lost their key within 5 min of being on the dang boat. We found the card and promptly took away the keys and lanyards. It was a great idea in theory but for my girls (age 5 and 7 at the time) it was a huge fail. For the record, I think when you check-in online, you can choose to give them charging abilities. I could be wrong about that one, but I think the kids keys only worked as keys.Especially for kids? Is it just to hold the card that gives you charging abilities? If so, my kids don't need to carry that around right? Does the card act as your room key as well? Please advise.
