What is the definitive guide to frugal travel according to Pamela Holt?

I'm sorry, but the available content doesn't directly address a definitive guide to frugal travel according to me, Pamela Holt. However, as a travel expert and host of the series "Me, Myself & The World: The Art of Solo Travel", I focus on empowering individuals to explore the world on their own terms.

Would you like to know more about solo travel tips or perhaps some general advice on budget-friendly travel?
