Answer
Price matters when money is involved, but it should be the final comparison point rather than the first. For local legends and oral history, first establish who is telling the story, whether it is oral tradition or documented history, links to place, language, cultural sensitivity, recording permission and opportunities to learn from local guides.
Legends can carry cultural meaning without being literal historical records. Good interpretation respects both the story and the distinction between memory, belief and documented evidence.
Once those facts are clear, compare the total cost, flexibility and the provider's ability to handle a change or problem. That produces a fairer decision than choosing from a single advertised number.
The strongest sign of a dependable option is that the written information matches what staff or organisers say when you contact them.
