My overall advice is to try and have a little foresight. As to be expected, when you have masses of people in one place the internet can be a little sketchy. Look through the schedule at breakfast one morning, find who’s going to be there the week before.
If you have children, feel free to bring them, you will be making memories but make sure you work in a little adult time too.

If you are going to take the time, travel, purchase the tickets, make the cosplay, find the babysitters and book the hotel rooms for Dragon*Con you really should enjoy yourself and make Dragon *Con work for you. So happy planning and see you next year!
