We were recently in Inverness. Now, I know Hogmanay is thought to be sacrosanct in Scotland by those South of the border, and the rest of the globe, but not to the extent where a bus company, Stagecoach, can disconnect a whole city and then offer a Sunday service, (read highly limited into that) for the remainder of the period. Taxi services were on tariff three for two days, that means they could charge sky high sums for journeys on those days and a bank holiday tariff for the other days. Workers could not get into work without begging favours and lifts if they happened to live outwith reasonable walking distance from their places of employment. I heard of some workers being bused in by a taxi mini bus, paid for by their employers, if they lived a certain distance out of the city. Others had to pay excess taxi costs from low wages to get into work.
If you want to get around and about when staying in or near the city of Inverness, think twice before visiting the Scottish Highland capital during a holiday period without access to private means of transport. Its public transport services, in any case, are rather limited to its conurbations after about 6pm. If you're happy to be in the centre and take a tour when tours are functioning, you may be suitably catered for.
In Summer 2009, I met an Australian couple who had arrived in Inverness by car. They were seeking a city visit hop-on-hop-off bus. It only runs on Wednesdays, the tourist office said, and this was a Friday.
