I don't know if Paris needs Pandora or rather a whole makeover of the Studios park. You think DHS is a mess... That park is really cheap and it shows. They need to bulldoze half that park and start over. There are good attractions there (Rat, ToT, Crush, RnR but the a majority of the park feels like Six Flags on crack. I would imagine they could wipe out a 3rd of that park and put in Star Wars, Frozen, Carland, Pandora or anything really. The park needs help and it needs a reason for you to go there. Right now it doesn't have that. Perhaps they add some sort of nighttime show to the mix. World of Color somehow. As far as I know... They have the land to expand, but I'd be more concerned with how they make that park start to resemble something worthy of the Disney name.
