The youngest is a very autistic sensory seeker. 2 late teens, one mid teen and 2 nearly teens. Day out in Liverpool. Older 2 don't care as long as we do lunch or tea at Cosmo. Middle one likes titanic, all of them like the beatles and music in general. Younger ones love a science/interactive museum. Youngest really loves water. I would prefer somewhere in the warm if possible. I was thinking eureka but not sure if it would be too young for them.
