When attending one of my courses there are various accomodation options in and around Moretonhampstead. However I would recommend:
If you have your own transport:-
Just outside Moretonhampstead -
Blytheswood Hostel - A WW2 hostel cabin in the woods, great value, lovely owners, please say hi from me.
Within Moretonhampstead -
B&B Plus - Central classic B&B, independantly owned with a good breakfast.
Sparrowhawk Backpackers - Central Moretonahmpstead backpackers, probably the cheapest non-camping accomodation in town.
