Yes! Kids of all ages are welcome, however it will be a long night with very little for children to do. If you want to bring children to the Ceremony and not the Reception, that is completely fine also!
If your invitation states a +1, then by all means, bring a date. If it does not, we prefer it just be you, we have not accounted for extra individuals for food and seating.
Absolutely not. Cocktail would be nice, but we love you as you are, so come in whatever is most comfortable for you!
