List what is included
For Nyerere, check the return flights, pick-up, lunch and the park ticket. On a northern circuit, also read the details of the nights, the room type and drinks.
Compare using the same settings
Choose the same date and number of travellers for every quote. Divide a group price by the number of participants. Count separately any nights outside the circuit and the trip to the starting point.
Look at the cost of a day on site
Two circuits of the same length can spend very different amounts of time in the vehicle. Note the hours actually planned in each park before comparing their cost.
