Absolutely possible. Local taxis are very friendly and flexible

It is more suggest able to enquire with hotel person or manager instead of any travel agents. You can book your tour directly with hotel representative. Avoid travel Agents, hotel person will guide you more better then TA.

I am in Gangtok for last two months ,climate in Gangtok town is pleasent,you need light woollens,water proof light jackets and umbrella as it rains here at any time and weather changes fast.If you are planning to visit North Sikkim,carry heavey thermals,for visiting high altitude areas,clothing is provided by almost all hotels on nominal rent.

There area a lot of eateries on mg road the best would be take a sneak peak at a couple you would get an idea who serves better. I tried one of them but the guests there were complaining about service so j came out within 10 minutes ... so take a shot at a couple of them.

Hi 5 days is enough to see Sikkim. U need one day to see tshangu lake,Nathula pass and Baba Mandir. 1day to for rumtak monastery and local sightseeing. But take extra precautions while visiting Nathula pass as u have small kids & it's quite cold out there. But I will not advice you to travel to north Sikkim as it's quite tough and if landslide happens u are struck there. Overall u can enjoy Sikkim no problem people are good. Enjoy Gangtok & Sikkim

9.30.to.9.pm

sorry really don't know.

Yes it is possible buy it will be hectic schedule. For nathula pass, changu lake and baba mandir you need a permit as it comes under Indian Army. Before arriving in Gangtok everything should be ready as you don't have enough time. Try to contact local travel agents at Gangtok. They will also arrange permit for Yumthang valley. Please contact Lama tour and treks. It is situated at MG Marg, Gangtok adjacent to Sikkim tourist information center. Contact number of Ms.Binita Lama owner of Lama tour and treks 9832079292/9734983536 . She is a professional travel guide and we took shared package from her and it was a brilliant trip.
