Cake and punch

Cake and punch can definitely have finger sandwiches or fruit and veggies platters.

They usually only last a couple hours, not 4, as that takes you into meal time, which means you need to serve food.

I wouldn't expect your reception to last longer than two hours. Most people don't stay at this type of reception very long.

Finger foods/appetizers, drinks and cake. I think anytime before 3pm for the start of the reception.

I agree with PPs. Your timing is fine but the reception shouldn't be four hours. Especially not from 3-7. That dips dangerously into mealtime and I for one, would leave after two hours max.

Plan for it to be from 2-5 try to have a few simple apps as well and you're set!

You can have finger foods with a cake and punch wedding (it's preferred).

I would suggest starting the wedding at around 2 pm or so and no longer than 5 pm. You don't want to go into the dinner hour. I would say max 3 hours for the whole thing.

Way too long for cake a punch. Expect that people will leave by 5-5:30. Even if you add some hors d'oeuvres, people will still leave way before 7pm so they can get home and cook or get a table at a restaurant.

Ty ladies. I have a better idea now on how it works.

I agree with @OliviaP's timeframe. Also, as PP said 7 would dip into dinner time.
