Thanks for the responses! We rang the embassy and thankfully, they'd not done a thing with our passport. Not put in the pages, nothing. So we made the hour train there and picked it up.
Frustrating that they didn't bother to do what they said they would (on the website) but at least they had it in their possession, didn't drop it into the post late.
We would have loved to given more time than 1.5 weeks, but business travel precluded that. So we trusted the website.
Off to Amsterdam!
