Yep pretty much! I've been to WDW mainly in October & i personally think it's the best time to go

crowds are low-ish (sometimes half term week can be a bit busy but that won't apply to you) & the weather is perfect!
Personally i would say mid October onwards, the prices go down for Disney Hotels from the 2nd week. But half term week can a be a little busier, but it's nothing on Easter half term! The weather is perfect, not too hot just about right & the humidity is low.
