That's the reason I won't do DVC (that and the high annual dues). I don't plan vacations 6+ months out because I usually go multiple times within 6 months, and I don't really like planning multiple vacations at the same time. In my opinion, if you're paying that much money for a contract, you shouldn't need to be on the phone 6 months out just to get a room somewhere, let alone the hotel you want to be at.
For me, 4 months is my maximum planning time. I can still get the ADRs I want by just checking for cancelations persistently and usually I end up where I want to be. It just takes real persistency, which I luckily have because I'm a Disney fan, but if you don't have that persistency and you really want to eat at a specific spot, use Disney Dining Buddy or something like that. It's not unusual for me to also wait until well within the 60 days to make FP+ selections. Again, because I'm fortunate to go frequently, if I don't get on 7DMT (and I have no desire to meet A&E), it's not the end of the world. Same mentality with attractions. For me, rope drop and strict touring plans just don't work. I rather show up at 11am or noon, use my FP+s, do some attractions with waits below 30 minutes, use SR lines, grab lunch, see some shows and the parade, and then take advantage of later less crowded hours. I know this is probably heresy in the Disney fan community, but I'm in the minority in thinking rope drop is not essential and touring plans create stress.
