When it was offered originally, way back when, since we only did adult trips, we liked it. Didn't always use if for the TS every day, but often used 2 allotments for the Signature meals a few times during the stay. We liked the convenience, and usually got value out of it.
Of course, everyone's mileage may vary, but that's the way we did it and it worked for us. I would certainly do the math when it is available again, and weigh all the options, including my AP discount, which I didn't have back then.
Like it or not, it's a choice that no one is forcing. I've seen on some forums, (not here, thankfully) how people are just getting downright rude and personal with attacks when others don't agree one way or the other... glad it's not like that here.
