Hang in there. I know it is tough. Your mom will hopefully realize how important it is to you. I think we see this as a common issue with Disney Weddings, one side of the family or another doesn't like the idea. It really goes back to what you are willing to do. You may not have that happily ever after with keeping your mom happy vs not. I think you have to figure out what to do the worst case scenario. I had this same issue with my dad. We paid for the majority of the wedding ourselves. We invited my dad and stepmom to our planning session so that they could see what went on. That this was not a joke. My dad to this day talks about how wonderful it was. Keep the faith and try and explain to your mom that you want her to be part of this and help her and that it is really important to have a Disney wedding. I know that you are going to make it and we are here if you need us.
