Legoland and london

[wishingchair1]

Hi, hoping you can give me some advice.
We are going to legoland at the weekend in a couple of weeks. On the Friday, I have booked a hotel in slough. So fairly close to get a early start.
We are thinking of staying somewhere on the Saturday evening and possibly going to the Natural history museum on the Sunday. We will have our car, so looking for advice to where to stay that doesn't take ages to get into London but able to park.

Suggestions would be gratefully received. As are tips on how to get the best out of Legoland. Oh and we are not set on the Natural History Museum. We have 2 dd age 6 and 9. Thanks

We can easily spend a whole day in the scienve museum and the wonderlab... And have spent more than a day in NHMuseum..

Thanks all. Think will just go with the flow. I want to do a musical another time, so no rush to cram it in.

You can eat sandwiches in a big room next to the Wonderlab. Also cafes in museum. Take plenty of water as they have taken out fountains and replaced them with vending machines
