Rasterise all vectors option in the export PDF dialogue window.
I use lots of detailed vector files in my layouts and when producing PDF's for approval this can be an issue as the files sizes can be too big to send back and forth over email. There are numerous work arounds but none really give a seamless document flow that should happen. Making a JPEG of my files and placing those instead of eps or ai files can be a headache also.
We will reach out to you in case any information is needed.
