So he's on vacation now? Personally, I would be really hesitant to interrupt my T's vacation unless there was an emergency. It sucks that you have to wait till he gets back to straighten that out though, I know it's hard to have things so unresolved. Is there a way you could sort of compromise, either leave him a voice message or write him an email/letter while he's away? That way you get your part out now, and know he will receive it as soon as he returns. Just my thoughts. Good luck.
