Don't let the different time frame bother you -- dining at DL is a very different thing than it is at WDW. ADRs made well in advance are an Orlando necessity; in Anaheim, we only had reservations for two evening meals (one a meet & greet, the other Napa Rose). We had one lunch ressie that we didn't even really need, as it turned out we could have eaten when we wished even without it. Unless you're big on character meals, you have little cause for concern.
