Yup, depends. The hiker needs days. The bus seat warmer can do it in a day. In between somewhere the majority visit.

For us it has been the multiple days at Tek, to allow for possible weather, & simply a more laid back visit rather than a cruise ship styled rush, rush, rush. The animals don't care if you are on a tight schedule. They don't have duty stations. Where there is nothing today might have something tomorrow.
