Dinner controversy

If I'm understanding what you said correctly. I'd second what Hank mentioned. If you want everyone to hear the speeches you could do this right after the ceremony. Have some designated people who you're not able to invite to the reception do their speeches and then rest of speeches can be at the reception. Or you have an open mic session for speeches right after the ceremony.

Why can’t people hear your toasts? Can you rent a microphone/ speaker if your venue isn’t providing one?

I don't understand your question at all.

I read your post as saying that you’re having a smaller ceremony / dinner with a portion of the guest list, followed by a larger party of some sort to which you’re inviting many more people (eg a dance). If I’m understanding you correctly, I think it’d be fine to have people take the mic periodically during the larger party and deliver a speech. If your party is taking the form of a dance, I would have all speeches delivered in one or two “clusters” though (and keep them short and sweet!) Constant interruptions at a dance can kill the atmosphere! Good luck!

So you're inviting everyone to ceremony but not all to reception? Can the speeches take place during the ceremony?
