^ Awesome, and if it would get a problem we can always go separate ways in the park, so that won't be a problem.
A tip: if possible, you could go to Walibi a bit before the opening time, because most of the times Xpress is already running before the park officially opens. I'm not 100% sure if that's every day, but the last couple of times I was there, I could already have 2 rides on Xpress before 10:00.
