Will every Republican delegate select Trump?

I've spoken to a number of Americans today (I'm in Hawaii) and some have conjectured that Trump is so hated by the Republican establishment that at least some delegates won't cast a ballot for him. The rationale I've heard is that the GOP, or at least some of it, will be so satisfied with a majority in both houses that thay are willing to sacrifice the presidency given that it would go to such an utterly non-Republican candidate as Trump.

Clutching at straws no doubt, but any chance at all?
