The only Character dining that I can think of that’ll get you Mickey and Pluto is Mickey’s Tales of Adventure breakfast buffet at Storytellers Cafe in the Grand Californian. You should also be able to meet Minnie, Chip and Dale, all dressed up in like they’re ready for a hike outdoors. Of the breakfast buffets, I like Storytellers best because the food selection is generally higher quality, Storytellers Cafe feels cozy like you’re in a lodge, and is much less chaotic than other venues like Goofy’s Kitchen and Plaza Inn.
As for parades, the Main Street Electrical Parade just wrapped up its limited run about two weeks ago so I don’t believe there are any nighttime parades. If they ever bring back Paint the Night, it is a must see! There is the afternoon Mickey and Friends cavalcade, but we don’t ever make it a point to see it and usually return to the hotel for swimming or some rest during that time. If you’re going during the holidays, there should be a holiday parade.
I highly recommend
Disneyland’s version of Fantasmic - the Sailing Ship Columbia transformed into the Black Pearl, swashbuckling pirates, cannon fire, Sorcerer Mickey fighting a dragon, Mickey and
all his friends on the Mark Twain! It’s just an epic show! (And hey, maybe take DS on a ride on the Columbia or Mark Twain earlier in the day, or even onto Tom Sawyer Island.)
We usually splurge on the Blue Bayou Fantasmic dining package, which gets you a prix fixe meal at the Blue Bayou. I think you mentioned your concern that it’s dark in there. It is, but the cool thing about dining in the Blue Bayou is you’re inside the Pirates of the Caribbean attraction, and if you’re close enough to the water you can see the boats passing by. Everyone in your party will get a foam seat cushion with a Fantasmic design on it. Blue Bayou will get you the best reserved seating area, on the ground along the walkway right in front of the Rivers of America and centered to Tom Sawyer Island where all the action happens, but prime spots up front are first come first claimed. But because those seat cushions are bulky, you may want to time any reservation closer to the 8 pm time to get seated for the 9 pm show, or around 10:00 pm for the second 10:30 showing, so you’re not lugging those cushions around for too long. If the Blue Bayou menu or price don’t appeal to you, the River Belle Terrace offers an upgraded dining package that seats you outside on the terrace overlooking the Rivers of America, where you can watch the show while you enjoy your dinner. You need to call into Disneyland Dining to book this package and I believe it’s for the first 9 pm showing only. Disneyland Dining can be booked 60 days out, and Fantasmic dining packages get booked up fast. Hungry Bear offers a dining package, but I don’t think their reserved area is very good and you might as well save your money and pull a Fastpass for Fantasmic. The crowds really thin out by the time the second showing runs at 10:30, so you should be able to get a good view then even without spending a lot of money on dining packages.
