I may be missing something here--but if you can book at 7 months out, no one will have an 11-months out advantage...everyone (home resort owner or not) will be at 7 months (or less)...
Key to booking is date of stay, not date of booking or use year...so for it to be 11 months out (again, whether or not it's a home resort owner), the date has to be 11 months from the date being booked...
Does that help or did I misunderstand what you're asking?
I think I get it but not sure, never did it at 7 months. So lets see I have Nov 16 and 17 booked but need to get to the 19 th. So on the 17th I can book the 18 th but unless there are more rooms open for that date (17th) no one can get the 18 but me since I have the 17 th booked. ( even 11 months owners) correct!
I'm I confusing you yet, I'm trying
Also, in general, everything is first-come/first-served (within the home resort booking advantage parameters)...so yes, anyone who can book a particular date can book it ahead of you, even if you're "walking" the reservation...it's all in the luck of the timing of your visit to the website and/or phone call...
