I did it last year, and I managed to get a reservation on my birthday, about 2-3 months before. I have my second one scheduled for next week, which I managed to pick up a week or so ago. I'm a single person, so it's easy to squeeze in, since it's so limited availability. I'm guessing both the times I got it, someone cancelled, or reduced their party size. I've never seen it available at 180 days. Once your kids are old enough, they will enjoy it. There was a high schooler at my last one, who asked for college advice. I must say I loved who I got, he was a civil engineer, and as a fellow engineer, I feel like I was the only person sometimes who really understood what he did. Hoping for someone good this time. You may get some inside secrets!
