How long is trekking to Gosainkunda from Dhunche?

Are there any Nepal veterans over here that would like to share their experiences and suggestions with me? I'd like to go to Gosainkunda and followed by that, I am planning a trip to Dhunche. I have heard that the journey can be arduous. Can you tell me how long it takes?

The trek will take you a couple of days at the very least, and I am safe to say that this will not be in the most luxurious of circumstances. Can you tell me how you are planning to travel? There are various options and one is quicker than the other, as you will understand.
