What plans has the agent changed? If you are speaking about the flights, then the airlines changed not the agent. Is it a local agent? If it is make an appointment to discuss your concerns and you would like an invoice with a little more information. Keep in mind that the flights can change a few times before you leave,the agent has no control over that.
I have been to all 4 resorts and by far CSA is my favorite. You will have a beautiful wedding and a fantastic honeymoon. The wedding cordinator will make sure that everything is taken care of. Follow the thread for weddings, there is a wealth of information on there, and I'm sure everyone here will be more than happy to reassure you and offer advice.
