Has anyone volunteered for a week at the Elephant Nature Park in Chiang Mai? I would love to go, but as I will be travelling on my own for the first time I am a bit anxious to say the least. I would be flying into Bangkok and then going by train to Chiang Mai. I am 48 and reasonably fit, but I am quite a shy person to begin with, which is another reason that I am hesitant about booking.
