I am there during those same dates. I went ahead and made a few ADRs for things where I wanted to have something at a particular time (e.g., Crystal Palace before MK opens) or that I knew would be harder to get (e.g., Cinderella's Royal Table).
But I am also leaving several slots open so that we can play it by ear. We will probably go with mostly TS restaurants, but this way we can be more flexible and not have to rush around to get to ADRs. And if we have a few QS in there on some days, well, that's fine, too.
And even if you have your heart set on something that isn't available right now -- CRT is completely booked up now for that time period from what I can tell -- try again just a few days before your trip. I found that when we went last year over spring break, a lot of things opened up just a few days in advance (no doubt to avoid the cancellation/pre-payment fees). I was able to get a CRT reservation just 3 days before we went down, after seing NOTHING there for months beforehand.
