My (non attending) partner is coming with me and/or I have non-attending children coming. How can we buy rooms, shuttle bus tickets, etc?
If your partner is staying in the same room with you, and you ensure you booked a french bed or 2 bed room, you should be able specify her as a roommate. She does not need to buy a Drupalcon ticket or anything else, just have a user account on the Drupalcon site. If you come with multiple non-attending people (children for example), then feel free to book multiple rooms yourself on your own account. Again, they don’t need a Drupalcon ticket.
