Our DD has Marion and she is terriffic! She is a take charge person who will make sure things go according to your dreams. Just remember that they are VERY busy, so it may take some time for Marion or Linda to respond when you have questions. Marion met with us for the planning session and we went through the entire wedding timeline step-by-step. She will help you make decisions for every aspect, and I found it helpful to make a ballpark BEO in my own mind before the session. That way as we made choices we could kind of stay on track - Marion would give the options and we would weigh each out vs. our target budget.
The only surprise was that a few of the choices DD made were incorrect on the BEO when it arrived, and I noticed that they forgot to include the cost of the wedding cake. As other brides here have posted, it pays to go over the BEO very carefully. As a result of all our advance planning and with Marion's help, the total cost was just about what we planned.
