So it's my daughters 11th birthday in a few weeks. She was going to have a sleepover but her friends can't make it. I want to plan something really special for her (she's amazing and been through so much recently) but I'm not sure what to do or where to go. She says she honestly doesn't mind, but she is lovely and I want to give her a great birthday. We've done the usual touristy bits in London as well as all the major theme parks/Harry Potter studios. Can anyone think of anything that I might not have considered? We are in the south but happy to travel in the UK. Thanks in advance.
