Anytime you want a standard view or a Boardwalk view, it's best to book day by day. (FWIW, I definitely recommend it for Easter break - reports for this past Easter indicate some very crowded parks). Booking day by day will virtually assure you of getting the exact dates and room type of your choice without having to use the waitlist.
Do some manage to get standard view or Boardwalk views by booking with one call at 11 months? Yes. I'd estimate less than a 50/50 chance, though.
Do some manage to pick up one or the other at 7 months? Less than 7 months? Yes. But neither of these is at all the "norm" - IMHO, they called at the right time and were lucky.
If you do not like the stress of the waitlist and need to make air and ground transportation arrangements quite far in advance, book day by day for standard or Boardwalk views. You'll be glad you did!
