Is there anything else you would like to add?
Overall, the experience was poor value for money, the helicopter we were almost obliged to hire, cost 600 USD per person, with 100 USD returned to us for the unused plane flight to Lukla at the start of the trip.
This was considered well worth it by the group in general but, ironically, despite the continuous "Lucky we took the helicopter", it was more of an insurance policy because the flights continued the next day and we may well have flown in 1 or 2 days later. It may also have cost us the goal we sought, Everest base camp.
Because we started a day late, our schedule was almost the original schedule (Note: the extra day at the end was maintained, not for us but just in case the return flight was also delayed and we may have missed our flights home, which would impact Exodus).
This compression of the schedule meant less acclimatisation, which, for one person and her husband at least may have cost them the trip since she got serious altitude sickness and had to be helicoptered out.
When the cyclone hit, we were forced to go down the mountain. Has we started later, we would have skipped Gokyo, which would have made everyone unhappy at the time, but we would have, very probably, made it to Kala Pattar, the finest viewpoint for Everest, and possible even Base Camp. This may have had it's own issues of course.
Added to this that several people were ill from stomach problems, including me for the only time on any trek. Everyone obviously took precautions but the food is all provided by third parties and there is a lot of trust placed in their hygiene.
As pessimistic as the above may sound, I am happy to remember the beautiful sunny weather we had for the early part of the trip, the amazing views and scenery in general. I will still look back and be happy I went.
