To give you an idea, using the Resort Availability Tool, right now the entire 7-11 mos window (8/8-12/14) is available for all VWL room types (with the exception of Studios/2-bdrm lock-offs Nov 27-the Friday after Thanksgiving). VWL doesn't typically sell out outside of the 7 mos. window, therefore if you book exactly at 7 mos. @ 8 AM Eastern online you will have no problem whatsoever getting any room type you want. That said, October does go quickly, and Studios go first, and with them 2-bdrm lock-offs (which are a Studio and One Bedroom combined, therefore when Studios sell out implicitly 2-bdrm lock-offs sell out). Keep in mind a 2-bdrm lock-off have the following beds/occupancy: Studio side has 1Q, 1Q sofa, 1 murphy bed (occupancy 5); One bedroom side has 1K, 1Q sofa (occupancy for 4), whereas a dedicated 2-bdrm has 1K, 2Q, 1Q sofa -- thus more actual beds but occupancy for 8 vs. 9 -- something to consider.
As far as BCV, the dedicated 2-bdrms have two configurations -- 1K/2Q/1Q sofa and 1K/1Q/1Q sofa, and because not all have 2 Queen and there is a separate room type for these, these actually sell out before the 7 mos. window (one of very few room types that sell out in advance of 7 mos.).
As far as BLT or VGF, unlike VWL both 1 bdrms have occupancy for 5, and have 2 full baths vs. 1 full bath in VWL 1bdrms -- which depending on how many are in your party could save you over a VWL 2 bdrm and be closer to MK (5 minute monorail/walk vs. 20+ min. boat ride).
