My niece and nephew have never been to a musical and I thought I would treat them and my sister and my son. My son is a well behaved 4 year old, my niece is 7 and my nephew is 9 but autistic so cab come across younger. What musicals would you recommend? I was thinking long King but will they just think they have seen the film so don't need to see it. My sister is worried they will say yes now then not want to go and ruin it somehow. I think a trip to London is exciting and they will manage fine.
