We are relocating to London with a 2yo and a 3mo. With a budget of about 300k, I don't think wecan afford to live in London itself, so we're looking at commuter towns. We're considering St Albans, Welwyn Garden City or Hemel - does anyone live there? Are there a lot of young families and is there much to do with preschoolers? What is there in the way of facilities - leisure centres, libraries, der/dentists?
