Everyone will need their KTTW cards and adults will need a picture ID. No need to bring your birth certificate. You will of course need money and perhaps a credit card depending on what you plan to do in port - with the exception of CC where any expenditures will be charged to your KTTW card.
I bought a small waterproof DCL lanyard to carry things. I was able to fit our KTTW cards, DL's, a credit card and a few bills.
An open mind. I get tired of people complaining about the islands we visit. Just look for the beauty not the bad. Remember, you are on vacation, have a good time.
