For those trying to book dining reservations here's my experience. We are not staying onsite, visiting DLP in early August. Kids really wanted dinner at Bistrot Chez Remy. Noticed the next day's reservations opened up around 5pm PST on the app. By chance, I noticed a table for 5 opened up for the day before we planned to visit DLP so I booked it as shifting our schedule 1 day was fine. Lucky I did as I haven't been able to see a table for 5 open up on either day since. Just keep looking but your best bet might be 5pm PST, 60 days before your visit, if you are not staying on site
