With 4 adults (parents & 2 sons) going on the cruise, will we each receive a sail & sign card? and will each s&s card be associated with the one credit card? My sons do not have one.
You will each receive a card. When you board your pictures will all be taken and will be linked to each card for security purposes. The cards are your ID as well as a charge card. When you leave the ship in port you will swipe the card and when you return you must swipe the same card. The security personnel will make sure the name matches the face. The four cards will be linked to whichever credit card you choose. You can have as many people and cabins as you wish connected to one account OR you can have each person in a single cabin linked to separate accounts.
You also have the choice of whether or not to allow charging on the card. i.e. if you do not want your sons to be able to charge anything, they won't. If you want them to be able to charge, make sure to say so. Don't assume they will be able to unless you specify.
