From Plymouth to Princetown you can have just over 2 hours in Princetown. Have noticed a good number of passengers going to the tea rooms for lunch.I think one problem is that it does not have very good connections from Plymouth. Only 1 each way from Plymouth to Tavistock. If I want to go out to say Princetown or Moretonhampstead I barely have time for cup of coffee before bus back. I appreciate there is Stagecoach service 1 from Plymouth but this makes it very expensive to pay £6 to Stagecoach then the ,£10 Dartmoor Explorer fare to First
There are some short hop Single and return fares available alongside the £10 Explorer fare.
