It may seem a bit simplistic, but older people tend to go on cruises for several reasons e.g. travel to foreign countries without flying, having someone else do their cooking and cleaning, not using gas and electricity at home. These and other reasons will ensure that cruise lines continue to have healthy booking figures. At the time of writing this post Carnival shares are bucking the stock market trend and rising above $9 per share. Please do not write off Carnival yet, there is still a lot of mileage left in this company.
