Hello!
First of all I want to let you know how much I enjoyed this trip and my visit to Bhutan. Amazing country and people! Beautiful scenery!
Pema, Yeshey and Gudut were top notch! They went above and beyond in making sure we had a fantastic experience. And always with a smile and in the most sincere way. I would give them a 10 out of 10 rating! I think of them as my brother’s now.
All the staff that were part of our trek – the chef, 2nd chef, helpers etc.were so great! The food was really delicious and the service fantastic. I felt like I was at a first class resort!  The bonfires at night were a perfect ending for each day and the time when we got socialize not only with our co-travelers but with the crew. The trek was my favorite part of the trip.
A few suggestions:
*Make sure everyone has cash with them (rupees or Bhutanese ngultrum). We ran in to the issue of having access to cash when needing to pay/tip the local porters etc. Luckily some of us had extra cash to lend to others. We found that ATMs are not very reliable once we found one. Often out of service or not connecting with foreign cards. Very important to know so you can prepare and bring local currency or rupees with you. Also important to let travelers know that the Bhutanese currency can not be used outside of Bhutan like the Indian rupees can. 

*The trip program is wonderful but it would have been nice to have some more free time, especially the days we were in towns etc. There were a few times when I felt very rushed. It may not be necessary to visit every temple, Dzong etc.
