With the benefit of hindsight...
A daily route card with accurate distances & ascents would have been helpful. Exodus estimates & local maps are somewhat inaccurate.
ID badges for the guides wouldn't go amiss for the first few days. We were not sure who we are giving our baggage to on arrival at Kathmandu airport and the local names take a day or two to get used to.
The trip notes highlighted a 5100m climb to Nagkartsang (from Dingboche), the exodus guide recomended against it re: acclimatisation. We went for it feeling fit but suffered somewhat later. Trip notes & agenda read in advance of the trek should match the advice given on the trek.
The walk from Dingboche to Lobuje without a food stop is a fair slog, a packed lunch could have been organised?
A breakfast snack should be offered before climbing Kala Patthar at 04:00hrs - collapsed at the summit!
Don't get me wrong... a truely excellent trip and will be back for more!
