so...what to do in London for a weekend with the kids?

[Lua]

I have to go into London for business on a friday and I was thinking about bringing a 5 and 3 year olad along to do something fun in the weekend.

What should we do? and anyone knows a cheap but nice hotel for kids?

cheers!

Not v original but I love the Science Museum - the garden section is v hands on for little ones and also the Launchpad. There's also a loo with a model poo in that you can flush and watch how it works. DSs age 4 and 1 had to be dragged away from it after about 20 mins of flushing. Natural History Museum also fab. Then good to go to Princess Diana Memorial Playground in Kensington Gardens, with excellent pirate ship.
Sorry don't know about hotels.

thanks!
Love the suggestion of having a scientific visit to the loo!
