Hi Justin! Welcome back to planDisney! Thanks so much for sending us another great question!
With Disneyland being Walt's original park, going on a tour is a great way to spend time at The Happiest Place on Earth! As you mentioned, A Story of Celebration: 70th Anniversary Guided Tour at Disneyland Resort usually includes a reserved viewing spot for 
Paint the Night Parade. During the 
Holidays, you will have the opportunity to enjoy a reserved viewing area for a nighttime spectacular with this tour. While I anticipate that the reserved viewing will be for 
A Christmas Fantasy Parade, I can't say for certain which nighttime spectacular you will have reserved seating for. As your visit grows closer, I recommend 
checking the page for A Story of Celebration tour for an update about which nighttime spectacular you will be able to see with reserved seating. 
Before you arrive, be sure to check out the 
Holiday Guide from Disney Parks Blog! The Disneyland Resort has so many holly jolly offerings, and the guide is a great way to check out what's happening during the most wonderful time of the year. 
If you have more planning questions, please feel free to send them to us at planDisney. We're excited for you to experience the magic of the Holidays, and we would love to help!
Wishing you magic,
Lisa
