1. First see if any images are much higher than 300dpi. This could just be a drawing problem because of the size of a photo / pattern swatch, or transparency.
2. Open you work in Acrobat. - Save a copy (just in case). - Then go to Pre Flight and analyze - look for error messages.
Acrobat can often fix these issues easily.
3. If that doesn't work, you can flatten the art (but this is destructive so make sure you have a backup). Flattening transparencies is either VERY easy or nigh impossible - depending on the file. You can try flattening everything at once or you can open in illustrator and flatten problem layers separately.
I have downloaded the file and checked it.
1. There is only vector artwork in it. But just a lot of it. And transparency. It's even slow in Illustrator.
3. When you flatten that specific artwork, you will end up with even more paths, which will slow down the presentation even more.
