I called back to change an ADR or two and checked to see if I was able to reserve places on 7/3 and 7/4 (for the 3rd time) and I was able to. Don't know why on the two previous attempts I wasn't able to, but found something out as well....I tried to make ADRs for Wolfgang Puck Cafe on 7/3 and wasn't able to because it's not owned by Disney. Apparently, the non-Disney owned restaurants will only allow you to book at exactly the 180 day window or less.
