We are always there to watch the park open...I've always felt like it sets the tone and the mood for the whole day...I think it helped our daughter maintain good behavior for most of the day when we would go because of this (she was 2 and then later 3).
Not really a tradition, but we would either eat sandwiches and drink pop (well she drank water) from our own cooler at Ariel's Grotto (we always appreciated Disney allowing this) or we would eat at uh.....ok...my mind just drew a blank.....Harbour House??? Where they have the Starboard Deck sandwich, I think that's Harbour House. We always enjoyed doing either one of those.
We also just didn't feel like it had been a "normal" trip to Disney unless my hubby and I watched people eating HUGE turkey legs in the 100 degree Florida sun.....it just doesn't seem right. We loved watching people eating those things and trying to stay cool at the same time..it's just funny to us.
That said...I've secretly wanted to try one but just never did...I either wasn't hungry or was too hot or something or other!!!
