No, there's no B & B...just kidding;P Again, there are no resorts/facilities on the islands. However, we met some people who have stayed and camped overnight. Before you try this, possibly get more info from the resorts in Pundaquit/locals to be sure it's safe to do so.
like from wat is posted there are no resorts nor electricity in the island.. u can have a bonfire and do some ghost stories which is very conducive to have it. bring some battery operated stereos and have sound trippin...
