Of course it is worth having. I have been there twice before and after, once stayed at Feilai Temple for two days, went to Yubeng for a circle, last year to Feilai Temple after going to the north slope of Meili, and stayed at Feilai Temple for two nights. Speaking of seeing the Meili Snow Mountain, Feilai Temple is of course the best angle, and the sunrise and sunset of Kawagbo can see your visual fatigue.
