Every week a Guardian Money reader submits a question, and it's up to you to help him or her out – a selection of the best answers will appear in next Saturday's paper.
This week's question:
Four of us are flying out of Stansted airport and I'm shocked to see it costs £126 for train travel to and from London. I'm going to drive and need the best options for parking. Friends use a valet parking service. Are they as risky as they sound? Is there a better option?
What are your thoughts?
