I requested additional information some time ago and was answered quickly by email. Then I kept getting emails announcing sales and getting a promo code. I called Diogo because I couldn't get the promo code correct and he sent me an email with the tour I wanted at the sale price and with the promo code discount so I was able then to just click on the link he sent and got my booking made. I am happy with the booking service and if the tour itself goes this well I will be very happy. It's a trip I have been wanting to take for awhile now. Looking forward to it.
