No flames just observations
October is not that much cooler than September, if at all. Have been to WDW in Oct. & Sept and honestly, October was much hotter in 2005 than any other time I've been (however, 2006 was wonderful..last week of Sept.)
Food & Wine festival starts in October, so when speaking of crowd levels, I believe you are way off. It will be much more crowded during F&WF than during any promotion in Sept., imho
Considering going a few weeks earlier than planned is not necessarily letting a marketing idea dictate your vacation, but "influence it's flexibility"
Not just during a
free dining promo will you be limited to dining times at choice Disney TS restaurants. That is true all year, and Especially during F&WF.
It will be decorated for Halloween during the last 2 weeks of Sept through 10/31, AND even having
MNSSHP's during that time
Crowd levels in the restaurants during the free dining promo is going to be high, granted. However, the parks are empty and WONDERFUL! Honestly, at most TS restaurants, they will be packed at all times due to heat and ADR's; free dining is not as impactful as one would think.
OK, there it is. My response, I'll bet you can see what my opinion is of free dining
