If we included them on the invitation then yes they are. Fairly certain that includes every kid. If you want a night out without them that's your call
Travel will not be provided, however the venue is rather close to the hotel. Feel free to hire a Lyft or Uber driver if you do not have a ride or check the travel page for details on car rental suggestions.
If your invitation says “+1,” then yes, if not, we would prefer if it was just you.
Casual. We want everyone to feel their best selves so don't worry about that stuffy suit or incredibly tight cocktail dress- unless that's your jam. You do you.
There will be a valet service at the wedding to handle all of your vehicular parking needs. There is no room on the dance floor for a parking lot so its just across the street.
