UK and Scotland by Train

At this moment, I am thinking that since I will be attending a conference in the UK for 3 days I suddenly thought about prolonging the trip by buying BritRail FlexPass
and travel all the way to Inverness. I found out from the Britrail site that a 4-day Flexpass anywhere in UK and Scotland costs around 203 Euros (4 days), 294 Euros (8 days).
