Not too bad if you're not actually overlapping Thanksgiving....
But general rules of thumb:
- "View" rooms will have more availability, cheaper "standard" rooms will be harder to come by..
-One bedrooms will have the most availability.
-"special" rooms like Riviera Tower Studios, Animal Kingdom Value rooms, Animal Kingdom Concierge rooms, will mostly be gone before the 7 month mark
-Epcot area resorts, specifically BWV and BCV, can be difficult at 7 months during Epcot festivals
- And obviously, holiday periods will be harder, Run Weekends, etc, are harder.
For the most part, if you're looking for a 1 bedroom room with an upcharge view at 7 months, you will typically have options. Looking for a standard studio, your options will be far more limited.
