You didn't say in the post, but I assume you're talking about the Princess breakfast in the castle. I've been fortunate enough to do this breakfast and lunch a number of times, as well as Breakfast and Dinner at Akershus in Epcot. IMO, lunch is better than breakfast at the castle. My advice is to read all of the threads you can about the process and burn up the phone lines the first morning you can. I can't tell you if this is nearly as difficult to book now with all of the price increases and reservation changes in the past 6 years, but when we were doing this every trip with our little girl, time of year was irrelevant. In other words, it was always difficult to book. If you can't get breakfast, don't shy away from either lunch, breakfast/lunch/dinner at Akershus, or dinner at 1900 Park Fare. To me, they are all good choices.
