There are numerous accommodation options on Shetland from hotels, B&B to self-catering cottages.   Before deciding on accommodation, it is best to have a discussion with Richard on the best area to stay for where the otter/photo tour would be taking place.  Richard can recommend places and book the accommodation for you.  The website is a searchable website for accommodation across Shetland, from the most basic camping böds in the peace and quiet of the countryside to luxury apartments in the heart of town.
