All the time any advice to maintain any sort of distance between people remains it would be an absolute nonsense to consider operating pretty much any rides.
The point of the distance is to prevent the virus transfering from one person to another. While 2m works as general advice, designed to be a mostly workable and mostly effective alternative to total isolation, it stops being effective once you start travelling at speed through another person's space, especially while you are screaming with your mouth wide open!
There is no point at all in standing 2m apart in a queue, then sitting 2m behind on a ride travelling at 60mph. It'd be the equivalent of sitting on each others laps in terms of virus transfer risk.
Thinking of Towers:
Nemesis, Rita, thirteen, Wicker Man, Galactica, RMT, Octanauts. NOPE! One row per dispatch, can not be worth opening.
Spinball, Rapids, Duel, Gangster Granny, Skyride and the rest of Cbeebies would be fine, one group per dispatch.
Hex would be somewhere under half capacity, staggered rows of groups with everything up to the ride as a free flow walk though. So it'd be crap.
Dungeons is a no, Sealife with a tiny capacity.
I cannot see it being economically viable to open until a time when the government advice does not include maintaining a specified distance between people from outside of your family group.
