My reading of it is that it can be shared with one other person per wallet, so i can have one other registered on my account only for the 10 journeys. There is supplements to pay each journey through the wallet costs £48 plus £12 if you are a MH Camper. £18 per dog if you have one and either £20 or £30 depending on travel time peak non peak. Off peak time no supplement charge. Have copied table from their site below. We tend to travel off peak times with a dog so think it would be £78. I suppose it depends on how many times you travel and at what times if its worth it. Kenny.
