Rewind Henley - Campervan

We've been glamping at Rewind for 5 years and thought we would hire a campervan for something different. Anyone on this forum stayed in the campervan area?

Is the walk to the festival 10-15 min? are there loos and showers shared with the camping section or the glamping section or does the campervan section have its own loos and showers. And what is the extra £88 campervan cost for if you are already buying the camping and entry tickets? is it worth taking a campervan or just sticking to what we know with the glamping - any advice appreciated before I book tickets and campervan.
