my partner and i just came back from Bonigen travel from Zurich via Berne by train excellent, my partner uses a w/chair and encountered no problems, we stayed in the Seiler au Lac one room for disabled but not really suitable though we managed. free bus from hotel with ramp access, all rains from Interlaken accessible though had to be lifted off at various mountain stations. all boats accessible, stunning scenery, but a bit quiet in Bonigen. food and other hotel facilities good. if you need a relaxing break with stunning scenery highly recommended.
