Thank you for responding and the link to the training site . With regard to the berths , we have drawn up a wish list but accept there will be some trade offs . We could certainly live on four permanent berths ( we have two grown up children who will join us from time to time ) With perhaps the opportunity of converting part of the lounge when needed which will be less frequent . The plan is to spent maybe six weeks in the spring and another four in the autumn travelling with a number of long weekends in between, we live near the grand union , Rickmansworth is closest town in the water and for the next two years , assuming we get through the pandemic will need some access to London , after that the worlds our oyster.
