Travelodge

My DH wants to climb Ben Nevis in September as part of a series of challenges he's set himself for this year. However, to stay in a double room in a Travelodge in Fort William is a whopping £571 for three nights! This is supposed to be a budget hotel! We regularly stay in a Travelodge in Tolworth not far from London and usually pay on average about £50 - £60 per night. Why is Scotland so much more expensive than somewhere just outside our capital city? Is everyone going up the mountain??!! I know I'm not!!!
