DO NOT BUY ROYAL CARIBBEAN GIFT CARDS UNLESS YOU ARE USING IT TO PAY FOR THE CRUISE FARE ONLY
They call them gift cards, but they aren't really. Even though RC has a section on their website to pay with a gift card, this is not really a gift card that AARP sells. It's some other nonsense that is actually far more restrictive than they even disclose when you buy it. So much for AARP looking out for the good of its members.
