with a journey planner Geogri (I think that's spelt right) linked on a different thread I noticed from Euston train station to the ExCel center had zones and I (while checking train tickets) got asked if I needed to buy all day train tickets and it goes by zones. and I was wondering if anyone knows the Zones I should pay for is it just 1 and 2 or 1,2 and 3 not sure, was thinking just get 1,2 and 3 to be safe but if anyone knows would be a big help.

thanks =)

OK, firstly you should a Travelcard when you get Euston Underground. This will let you get Bus, Underground and DLR. All the public transport in London is run by the same people so the card crosses over. That is important as the DLR has its own fares.

The card you need is for zones 1-3. Euston Station is in Zone 1 and the Excel Centre is in Zone 3.

I take it you are staying for both days, right? You might want to get a 3-day travelcard. It will make it easier for getting back to the station, if you're not staying nearby.

thanks for the help Ice-climber
