hi, I'm trying to get my trip to Tanzania for this June 2006 booked. However, the operator I was first considering of working with, has told me that for some of the most important parts of our trip, rooms can not be confirmed yet, and we would have to stay on a waiting list. And we would have to pay our deposit before even getting final confirmation. Which are the operators that work with block reservations, in other words, are able to quickly confirm your rooms ? Is this the normal way of working ?
