It depends if you think Maus au Chocolat is quality.
For me I tend to avoid it at Phantasialand as it's just screens and an RSI by the end.
Maus is probably an expensive ride system, Disney use the same one for Toy Story Midway Mania at DLR/WDW/TDR - something a little simpler would probably do Paultons Park. We know how easy it is to fritter money away on dark rides that don't even end up being that amazing.
True! I do, I think the ride system is great fun though, and would suit Paultons perfectly.
I wonder if it is really that expensive? The Disney originals which included the R&D obviously would have been, but as an off the shelf system it is now I imagine it should be within reach.
