TSPL is great fun, smaller attractions for kids, theming is great too.
Last time I was in Paris the queue for Crush was too huge we didn't get time to ride it. But it's popularity proves it would be a good addition to DHS.
My only gripe would be if they laid it out as poorly as DLP, the queuing needs sorting big time!
Ive not had chance to do the backlot tour, so I am a bit gutted it'll be gone before my next trip, no matter how tired it's become!
