Hi :-)
I have done the Mohare Danda trek October 2016. We used 6 days for this trek. But it can be done in 5 days. We planned to use 5 days, but since I became a bit sick (a cold and probably a bit because of the height), we decided that we needed to split the day from Mohare Danda to Tikot into two days. It is a good trek. :-) Please remember to start early from Pokhara the first day. We started too late, so when we came to Beni by bus, it was too late to walk up to Banksharka, and we had to be driven up there (which was an experience in itself, as the road is far from good). It could be good to call in advance to Banksharka, so that they know you are coming. But this is not necessary.
BTW: Willelmspie wrote that you need to carry food for lunch. This is necessary for the day going from Nangi to Mohare Danda. But you do not need to carry lunch on the 2nd and 4th day. I am a bit unsure about the 5th day, as we were going to Tatopani and not back to Pokhara that day. Maybe the bus normally goes to Beni hourly, but it did not the day we took the bus, cause we waited probably 2 hours on the bus station in Pokhara. We did not check the bus schedule before going, and I would recommend that you do. Or you could take a jeep all the way to Galeshwar.
Enjoy your treck :-)
