Dont say anything, act totally fine with it and ask him to email them to you so you both have a copy that way there can be no confusion. He may just be trying to stick his feet in the mud and not agree to what you say, you know what they can be like about pride sometimes. Tell him you'd prefer his suggestions by a certain day as you need to have a look, but until then you'll stick to the plans you have made.
I know this is going to sound horrid, but apologise, say you assumed he had the emails, but you're happy to see his ideas, as long as he is happy to change the arrangements for now to your suggestions, explain it is due to kids schools etc and be uber reasonable.
You can always punch a pillow and scream cunt poohead at the top of your voice once the onversation is over
