Yes. Offsite, locals, anybody can book at 180 days from the date you want to eat. If you're staying onsite you can book up to 10 days before that, depending on when your checkin date is.
Actually TDC Nala, if you stay on-site it's still 180 days from your first day. The extra 10 days is from that point on so you can book your ADRs at one time instead of calling 180 days from each day of your visit.
