Hi there!
Did you have the UK wedding package by any chance? I am pretty sure that the North American package does not allow for both the Disney and the outside vendor to be there at the same time. And there has also been a difference in the photo packages in the past, too.
Also, we will be traveling from Canada for our Intimate and have tried to contact Ryan from Total Imagery several times and did not ever get a response. I think he only works exclusively with UK weddings through Virgin for Disney weddings.
But as mentioned previously, DFTW will allow you to swap the 2hr coverage for a Honeymoon session.
In regards to having two photographers present for the wedding, it's best to check with your EM to be sure!
HTH!
