Hey there. As you probably know, it's coming up to the summer holidays! I'm going to be travelling to Lakeside a lot (near the Chafford Hundred station) and am looking for the cheapest way for me to get there. I'm 16-years-old and currently reside in Shenfield, near Brentwood. The people that I'll be going with live in Hornchurch but I don't necessarily need to meet them there; we can meet at the 'start' of the journey (i.e. Romford/Upminster?). I'm just really wanting to know the cheapest possible way for me to get to Chafford Hundred from Shenfield and, if it involves an Oyster card, how does that work? Thanks in advance! Conzy. P.S. My friend said he can get a free bus from Romford to Chafford Hundred with an Oyster Card? I can travel with buses if that's cheaper/easier.
