Okay, I had success! Except the only times available were like "morning to early lunch" and "very VERY late" at the popular places again. It's quite weird- as a 1-person party I figured it'd be easier to find a seat for dinner times, but I guess not! How many other people book 10+ day vacations and can book dinner that far out ahead? Though I changed my #s to be 4 people and suddenly EVERYTHING popped up- I could easily have booked tables for 4 at any time!
So I landed:
Lunches at Be Our Guest (swapped it to Dinner by pretending it was for 2, then subtracting one person, haha)
Lunch at Cinderella's Royal Table
Dinner at Tiffin's (only the barest idea of what that is but it's something new!)
2 Dinners at Jungle Skipper (did it always have that "Navigation" in the title?)
2 Lunches at Akershus.
Dinner at Boathouse
Not bad at all- heck, it's honestly easier to eat the big meal early when the parks tend to hit peak busy times anyhow.
One weird wrinkle- my vacation is 11 days, but I'm only allowed to book up to 10 days after, I guess? I didn't realize that one- I kept thinking I messed up cuz I couldn't book May 16th for anything yet!
