The Griswalds are returning to Wally World?

We finally have a snippet of synopsis from the upcoming instalment/reboot in the "Vacation" franchise. Plus, who doesn't love a bit of Ed Helms when he isn't starring in the abominations known as "The Hangover Part II" and "The Hangover Part III", he will be a great fit for Rusty here's hoping that we get to see Chevy Chase return as Clark Griswald.
According to Crave Online;

"It’s another road trip back to Wally World,” Daley said. “He realized that his original trip to Wally World brought the family, the Griswold family, closer together and he kind of chose to forget about the horrible moments along the way and decides that what his family needs is some bonding time and wants to take them back on the road again. Safe to say the road to Wally World has not gotten any easier.”

Going back to the destination of the original Vacation is both reassuring, and risky. The writers felt there was new ground to be mined from returning to Wally World. “I think it was always part of our intention,” Goldstein said. “We felt like in continuing a franchise like this, there’s a certain amount of homage you have to pay to the original but we also wanted to make this very much its own movie that can stand on its own. So we chose our favorite elements from the original and then used that as a springboard. I think people have an affection for the whole Wally World component of the story.”

Rusty’s family vacation couldn’t play the same beats if it wanted to, because Daley and Goldstein changed his family dynamic. “As opposed to going along with the same family structure as the first one with a brother and sister, now Rusty and his wife Debbie have two boys with their own very unique dynamic,” Daley said."
