I just hope in 5-10 years time when the reride-ability is at a minimum Merlin take a leaf out of Disney's book and give the ride what it deserves, a refurb.
I just don't think we get these enough in this country, yes I know some can cost a lot of money and Merlin may look at it as a money waster, but I just think adding more to the ride, sprucing it up and re-marketing it to the general public again can only boost its popularity.
Look at what Epcot are doing with Test Track. Ok, its on a much larger scale, but they haven't touched the ride layout, they've just given it what it desperately needed, a new lease of life! It will give Test Track another solid 15 years of popularity.
Thirteen wouldn't need a total retheme, just more added to the experience, to bring it up to date. Who knows where theme park technology will be in 10 years?
