ORLANDO, Florida — The books are long finished, the movies are now over, but all it takes is one step inside the Wizarding World of Harry Potter in Orlando, Florida, to know that "Potter" is forever.

Still, despite the ever-flowing butterbeer and copious amounts of "Potter"-based roller-coaster rides, there's always room for improvement, even at the Wizarding World. After all, the "Potter" universe is just too grand to fit every single element into one theme park. With that in mind, when MTV News traveled down to Orlando to cover the red-carpet celebration of the "Deathly Hallows Part 2" DVD release, we asked the cast and crew to weigh in on which features of J.K. Rowling's imaginative world they'd like to see included in future park updates. Jessie Cave, who plays lovelorn Lavender Brown in "Half-Blood Prince," suggested a new means of transportation for the park: "I think instead of being allowed to walk here, everyone should have to arrive by Hogwarts Express. You wouldn't actually have to walk. It'd be just the most comfortable trip ever!"

James and Oliver Phelps, better known as the mischievous Weasley twins, focused on a different mode of flying — via broomstick.

"If it were actually possible, maybe [it'd be cool] for an actual Quidditch match to go on," Oliver said. "Something like that would be quite cool to watch if that were actually possible to do."

Wishful thinking, perhaps — the technology probably isn't quite there to catch a real-life golden snitch just yet. But the rest of the "Potter" cast tried to think in more practical terms, offering their ideas on attractions that could be added to the park in the coming years. Several of the actors, including Warwick Davis and Rupert Grint, suggested the Gringotts breakout as an excellent possibility for a roller-coaster ride.

"Wouldn't that be great? You could join Griphook on the cart," Davis, who plays the aforementioned goblin, said of his Wizarding World wish-list. "And it's already done!"

"The Gringotts vault would be a really cool ride, I think," agreed Grint, who played courageous hero Ron Weasley over the course of eight "Potter" films. "Also, the flying car!"

Some castmembers didn't need to look much further than their own reflections to find suggestions for Wizarding World improvements.

"I've been thinking of a ride, a Luna ride," offered Evanna Lynch, speaking of her own character, the loopy Luna Lovegood. "You know all of the creatures she dreams up, all of the creatures that she mentions throughout the books, I like to think that there would be a roller coaster, and each cart would be a new creature. It'd be in the dark and there'd be all these projections of creatures flying around."

"I don't know what it's like to be stoned," she added, "but I imagine it feels something like that!"

And Jason Isaacs, who plays Voldemort loyalist Lucius, believed it was high time for the Malfoy clan to get some Wizarding World love. "There should be a Malfoy ride," he said. "I don't know why there isn't a Malfoy House of Horrors that you can enter as Lucius and leave as Lucius post-Azkaban."

Of course, Isaacs wasn't the only one thinking of his own character.

"We all want a ride based on us," he said. "It's a fantastic place here. The only thing that's missing is, obviously, me!"
