Are you staying on-site? If you are there are a select number of reservations held back for on-site guests who weren’t planning on reservations when they opened up at 60 days. So if any of those are still available, worth calling the dining line to check.
If you’re not on-site, all of the above reservations that don’t get booked by on-site guests by the day before are released to the pool for anyone to grab. Also, many people who are changing plans will cancel the day before as well so I would check the day & night before & even again once more in the morning.
Our favorite on-site table service is Carnation Cafe for the great value, delicious burgers/American-comfort food/shakes. Blue Bayou is definitely worth seeing once (but I do find it slightly overrated as it’s so expensive for what you get). As for the rest, we like a lot of the counter-service/quick-service & snacks at DL so don’t often to more than 1 table service meal per 3 day trip.
