This website does not take payment and does not confirm a seat. The useful questions are the ones the pages cannot answer yet.
Ask these before you decide
Which date is open. What the price is for your group. What time hotel pick-up would be, and whether your hotel is covered. What is included and what is not. For trekking, what the walk asks of you.
