If your invitation is addressed "(Your name) and guest" then yes you may bring a date, if not, we prefer it be just you.
Absolutely! We have already accounted for young children of guests in our estimated guest count. There will plenty of games and other entertainment for children.
Dressy casual, please. We want you to be comfortable so nice jeans and a button down is fine, but we ask that you please do not wear shorts or a t-shirt.
While there will not be a full service bar for liquor, there will be a variety of beer and wine available, as well as a margarita machine.
