We were going to do a signature restaurant this year (and still may) but I agree leaving off the appetizer choice make it much less appealing, not to mention having to pay the tip out of pocket. The entrees are more but the math nerd in me says...
At $22 for an entree and $8 for a dessert somewhere else and...
$35 for and entree and $8 for a dessert at a signature restaurant you are basically using and entire TS credit to get a $12 'upgrade' on your entree. I think I'd rather have two whole meals. Seems like a much better value.
We still may do it one time this year, but I will regret not doing it in years past. We've done Hoop Dee Do, Mickeys BBQ and the Poly Hawaiian show (sorry, drawing a blank) all for 2 credits a piece but this year since my boys are a little older I was looking forward to doing a nice 2 credit meal with them, but I will have to argue with the number cruncher that lives in my head.
