I'm new to
DVC too! I went in August, and my group arrived about 45 minutes before HEA. We were able to sit at one of the high-top tables...and there were plenty of other tables and couches open. I personally like to get there early to share some apps and drinks with my family before the show starts. Also, they'll put a little sign on your table if you want to go out on the balcony and watch the fireworks, so that no one takes your spot.
