Re Yumthang/Lachung

Hello,im a lady travelling alone to Sikkim...i%26#39;d greatly appreciate it if you can help with the following:

1.Is public transport ok in the daytime for transfers n sightseeing trips to Pelling,Lachung,etc?

2.In order to save money,is it possible to visit Chopta Valley,and Yumthang on the same day?Is Yamsedeong worth visiting?

3.And is Sonam Palgey a clean n good option?

Many Thanks in Advance!

Re Yumthang/Lachung

Could you detail your itenary please.Which Chopta valley are you referring to?

Re Yumthang/Lachung

Hello and thanks for your reply...from Gangtok drive to Lachung,i was told a 2 night stay is necessary..but i can pack in quite abit in a day,which is why i was wondering if its possible,unless of course distances are too far apart.

Im sorry ive never been to Sikkim,so im not sure if there%26#39;s more than 2 Chopta Valley...i was told that amn excursion to Chungthang,Chopta Valley can be done and for a higher cost,Yamseodang(spelling??!) and Gurudongmar can be arranged too and am wondering if these 2 sights are worth the extra cost??

Thanks Very Much!!
