As to April, there is some risk of having issues for getting a BLT standard view 2BR at 11 months out and for 2018 the issue might arise the first week of April which is Easter week and middle of April for time around the Star Wars half marathon weekend, and thus be prepared to move quickly at 8 a.m. at 11 months out. (Race weekends tend to be high
DVC demand times with the Wine & Dine half marathon weekend in Nov being the highest DVC demand weekend of the year, followed by the Jan marathon weekend, and then the Princess half marathon weekend in Feb which, though it is nowhere near as bad as either of the Nov or Jan weekends, is the highest DVC demand time throughout all of mid-Jan to late Sep, and the new Stars Wars race weekend in mid-April is quickly approaching it in demand.) Also what we do not know yet is what new special events Disney may be planning for Hollywood Studios annually in April after the park redo is done which could affect DVC demand for that time period.
