I'm planning on trying to get to Rafiki's Planet Watch during the morning (9:30-10ish) so we can try to catch one of their veterinary procedures. Aside from watching that for a little bit, how much time should I be setting aside to take the train in and out, peep a vet procedure, pet a few animals and look around? I have no idea how big that area is and I have no idea what to expect! Thanks!
