Where to buy London theatre tickets? Which show to see?

[Hulababy]

Might be going to London, just me and DD (5yo) in April on a Saturday. Have to see if I dare brave it on my own with her!

Was thinking of matbe going to see a show, but not really sure which sure or where. Or where the best place to buy tickest are?

I did think of Mary Poppins as it is DD's favourite film, but only tickets I can find available are £59 each, which makes it quite an expensive day out!

Any recommendations of child friendly shows?
Where is best place to buy tickets?

TIA!

HAve you contacted the theatre direct?
The Lion King is excellent for lo's too.

Lion King ticket price also appears to be £59. Is this the standard price for London theatres. Have onlly been once before and I didn't get tickets. It is a lot cheaper to go to the theatre up North!

Not tried direct.

Are you planning on staying overnight?
If so try a local coach tour place.
I have been to a few shows with hotel and coah travel included, and they have been really good value, about £129 pp.
Always nice hotles and good seats.

No overnight stay necessary. We will be staying at BIL/SIL's house in Hertfordshire and going in on train.
