TiW went up to $150 for AP holders and DVC members. It's $175 for Florida residents.
You still just have to do the math to see if it's worth it for you. If you'll spend more than $750 (as AP/DVC) or $875 (as FL resident) on food at qualifying restaurants in the course of a year's time at WDW, then it may be worth it to you. Of course, if you're AP/DVC, have a Disney Visa, etc, you have to take into account any discounts you might get as part of those programs, as well.
