We're finally deciding on what excursions to do for our safari in mid to late August, and two of our group really want to go on a hot air balloon ride (the other two are not so keen but are willing to along). We have time in our schedule to do this either in the Masai Mara Triangle (we're staying at the Mara Serena), the Central Serengeti (we're at Kati Kati) , or Tarangire (we're at Tarangire Safari Lodge).
Since the balloon ride is so expensive, we're hoping to go on one where we have the best chance of seeing lots of animals and have the best overall balloon experience. Any suggestions on which site we should pick? We don't really care about travel time from our lodgings to the balloon site if it's a better overall trip.
