At that price...
Worth it if:
Most days, you are doing a character meal plus regular TS.
Worth it if you drink wine or cocktails at most meals.
And as with any dining plan, prerequisite that it assumes you’ll use all the credits (95% for ts), get desserts at every meal, etc.
Not worth it for:
Signature dining without alcohol. (You need about an $85 signature meal to break even. Most signature meals are closer to $70-80 unless you add alcohol)
Not worth it for 2 ala carte TS meals per day, for most people. Especially non-drinkers. (Example....dinner, expensive $32 entree, $8 dessert, $10 glass of wine. Lunch, $20 sandwich, $8 dessert, $4 soda..despite making full use of the credits, you’re barely around the break even point at $82, not saving any money... had you skipped the glass of wine, you’d be losing for the day)
And definitely not worth it if you are going to use many credits for CS.
