It would make sense to have a older ship in reserve during the high cruise season in the Caribbean. That way if a ship is having problems it can be replaced and the problems properly fixed. Also the extra ship could go to the distressed ship, transfer passengers and save a lot of unhappy customers and future lawsuits.
Most trucking companies have this practice and is considered a must to keep their customers happy.
Women were made to love, money was made to spend. Life is something buddy, you'll never live again.
