How do i make decisions?

You have a couple of options; have a mid afternoon ceremony then a cake and punch reception, then have dinner with close family and friends. This is perfectly acceptable. Or, just don’t invite people you don’t want to invite and have a lovely small intimate wedding and do dinner for everyone.

It’s not a great idea to have a “tiered” wedding where some people are only invited to some of it. I’d think about having a small wedding and maybe have a brunch reception or a cake and punch reception at a non-mealtime. In any case, start with budget because that will determine the venue and amount of people you can afford to invite.
