Just out of curiosity, the last week or two, I have been getting online a few times a day and seeing whats open dining wise for breakfast, lunch, and dinner for the following day. Hard to get reservations for lots of places have been available every single day. We are going in two weeks, and I have had all my reservations booked for six months, but I'm just testing the waters to see what we would be in for if we ever decided to do a spur of the moment trip or plan one inside the six month window. I have been happily surprised at what I have found would be possible. Since there are so many choices, if you are somewhat flexible, I would be pretty confident that several options will come open a day or two before. Grab the first one that pops up for insurance and then continue checking to see if you can keep tweaking and find exactly what you want.
