thank you for the replies. I think I will go for a coach service for now. On days where there are after school clubs, can anyone please advice on what is the best option re buses and trains. Are there regular buses to go to Southend Victoria or Rayleigh and then get a train? Or is walk to Chalkwell and C2C the best option?
I have tried looking at bus information online for Southend and must admit its a bit confusing, with so many different bus companies? is there a good site that helps you plan routes etc?
Buses to Southend Victoria are the 29 (Arriva) and the 21/21A (First), catch them from the stop on the opposite side of Kenilworth Gardens from the WHSB / WHSG site. The 21 then carries on towards the hospital and SHSB, the 29 turns into Eastwood Boulevard (down the WHSB side of the site). The nearest place to catch a bus to Rayleigh is probably the First Bus 20 on Bridgwater Drive, about a ten-minute walk (via Mountdale Gardens down the side of the Tommy More site / Treecot Drive). If choosing between Rayleigh and Southend Vic I think I would go to Southend Victoria, personally.
As I have mentioned previously, an alternative would be to walk to Chalkwell (20-25 minutes) and use the c2c line to Upminster. Trains on c2c are generally more frequent than the Southend Victoria line. Or you could stay on the 21 / 29 to Warrior Square and start the journey from Southend Central (5 minutes longer on). the train than from Chalkwell
