Since they went to 3 character meals a day, CRT has not been really that tough to schedule, compared to how it used to be. It used to be that you could call straight up at 7 AM 90 days out (when ADRs were all 90 days) and you could be shut out.
That said, 2 months out can be pretty tough though. Keep trying. I'm sure something will come up, especially since you can choose from breakfast, lunch and dinner.
Check the online site many times a day. If you're a party of 3 but only see an opening for 4, book it, then call to have it adjusted to 3. Don't stop trying when your trip gets close at hand. Many wait until the very last minute to cancel. Try 45 days out, which is the last time people can cancel their trips without penalty.
Best of luck to you!
