If your invitation is addressed to your entire family, then please bring your kids. If it is only addressed to you and your significant other, its your night off!
If your invitation says "and Guest," then yes. If not, then we prefer if it is just you.
Cocktail attire please. The ceremony will take place outdoors on a grassy field, so please wear appropriate shoes.
We are having a unique dinner so we are trying to keep it a bit of a surprise. We can give you a hint: it goes great with margaritas!
