If I have a 7 day visitor travelcard, can a child travel free with me during peak hours too. I remember reading somewhere that a 7 day travelcard holder can take a child also along at all times; not necessarily off peak hours. Any input would be welcome.

Children under the age of 11 can ride free (with an adult) on the tube and DLR during off peak hours. Off peak is after 9:30 AM M-F, all weekends and holidays. See: http://tinyurl.com/kynn7

Children can ride the bus for free anytime. I'm not certain, but I believe the age limit for free bus travel is under 16.

You can get more information at the Transport for London website: http://www.tfl.gov.uk/

I was second guessing my answer about the age limit for riding on the bus. Children under 11 travel free on buses anytime, not under 16. Sorry.

Here's a better link with all the information you need:

Under 16. It's right there in the link:

"Children under 16 can travel free at any time on trams and buses across the entire London bus network, including sections outside Greater London."

Oooops! I know it's not a good idea to drink and post!
