Call carival and speak to one of there vacation planners.They will assist you on booking,answer any questions or concerns you may have.Once your all paid up nothing else to spend except alchol on ship,gambling in casino and money for the islands you may want to spend.Get them to include the gratuities in the price and you want have to worry with that at the end of the cruise.I suggest a 5 day minium but we like 7 days.The onesout of New Orleans are great.They have areas where u can leave your vehicle for long term parking.Way better vacation for your money than the beach !
