royal chitwan park in mid october

hi, read in the guidebooks that sightings of animals in October is difficult due to the tall grass, would it still be recommended to visit in mid Oct?

also, how do i get to Royal chitwan from pokhara? is there a night bus, how long does it take? or is taking a plane recommended?

and how do i return to Kathmandu from Royal chitwan? via tourist bus? is there a morning bus?

looking at spending ard 2 days at royal chitwan.

thanks for any advice!
