I received a mail today from Caribbean cruise line, and i was wondering if it is a scam or if it is real?? it says that i have been identified to receive a FREE two night cruise for two adults in the Bahamas. They also attached a cheque of 1,300$$ as a travel voucher. and they want me to call 1-800-305-8147 to activate it. is this legit?????? did anyone else receive a mail like this?
