Signatures -- On the deluxe dining plan, we have 3 table service meals x the number of nights. That's a lot of meals.... So, we enjoy several signature restaurants to use the credits and enjoy some finer dining. The average cost if paying out of pocket (for us) is double for a signature compared to a 1 credit restaurant... but it's still only 1 meal, not 2. I think there are many very nice 1 credit restaurants.
Next trip, out of 9 nights, we have 5 signature dinners - Citricos, Narcoosees, California Grill, Brown Derby, Flying Fish. With all the other character meals and themed meals during our trip... the signature restaurants are for mommy and daddy.
We could skip the signatures but our plan is to get out the door quickly most mornings and head to the park, not sit down for breakfast.
Shows -- I thought Hoop Dee Doo was fun and well worth 2 credits. We were in category 2 seating which was just fine. By the way, if you get Category 1 and are up close... you might get some spit from the actors (ever sit up close for a stage production?) Actors spit a lot when projecting their voices. Don't want that on your food! Mickeys Backyard BBQ was OK but more for kids. I actually liked Spirit of Aloha (the food and show) but I'd pay out of pocket to get category 1 seating. The category 2 and 3 seats give a poor view. The food was delicious and the beers kept a coming... Lots of "eye candy" during the show! if you know what I mean. And the fire juggler at the end made it all worthwhile... if you go, even if bored, don't leave until you see the fire juggler... they do save the best for last.
