At every TS restaurant we went to last year with our 2 year old, they brought us a plate and let my 2 year old order something. At CRT they did this, Chef Mickey's he got his own drinks and of course the buffet was free. I just looked on my receipts and it says "Under 3 Breakfast", so they do ring it up...but it's free. I don't have SciFi's receipt...so I can't remember what they did there, but it seems like they brought him something? Or maybe we split one of the other meals..not sure. Then again, most of the places we ate at were considered plated buffets I think? Like LTT and Garden Grill....so again, tons of food and he got his own drink and plate.
The only thing we had issues with were the CS's, but since we have a few small eaters among our 5 kids...we just split up all the food and everyone was stuffed and happy LOL
