When I'm solo, I make all my ADRs for two. Who knows-maybe I'll meet someone just before my mealtime whom I'd like to invite to have dinner with me. Regarding B&C, I've found it to be one of the hardest ADRs to get. DH and I are going to WDW in October, and it was the first ADR I made, right at 180 days. Even then, there was only one time around dinner time available the whole week we're there. Yet, the last two times we've been to B&C, the place has been about half full the whole time we were there. Maybe a few people didn't show up for their ADR, but that many?
