The only other info I can add is that for Tiverton where they have 3 rates... £5 for 1st hour, £10 for 2 hours, £12.50 for 2.5 hours. A genius system where you only paid for what you used on a day to say basis. And run magnificently. I can also thoroughly recommend their holiday scheme which is about £20 per day and has a great variety of trips and actvities
