I keep reading posts about people making all kinds of ADRs months ahead of time, or just ahead of time in general. Is this really an absolute necessity? I don't like to plan that rigidly, instead deciding which park on a whim (i.e. the night before where we are headed in the morning) and I don't ever make ADRs, except for once in a while for a special event, or if there's a specific time I want for a specific reason (plans for a show, to coincide with fireworks, etc.)

I haven't been in five years, but have things changed so much that I am going to be shut out by following what's worked for me in the past? If I do make ADRs, it's never been farther out than a day or two before as we're looking through guidebooks or parkmaps back at our resort.

Worth noting, I am not a hugely picky eater (neither is my travelling companion), and I don't mind eating outside of "prime" lunch and dinner times. It would also only be two people.
