I only go as a day visitor but would think location is the most important thing as the main road in Lyme is a very steep hill. Beautiful town though with great flat promenade and beach. Nice cafe at the bottom of the hill in a wedge shaped building that used to be a pub. If you do decide to get the bus to anywhere else, Pecorama in Beer is a great attraction for children and was always top of my 'days out' list when my children were younger. Hope you have a great time.
