Do you have any advice for potential travellers?
On this trip you have a lot of practical issues to consider, so be prepared. Here is my account of how I and some others managed on our trip, but please do your research and make your own preparations accordingly.
Health - The prescribed drugs that I took with me were amoxicillin, ciprofloxacin and acetazolamide, but I only needed the ciprofloxacin to treat bacterial diarrhoea that I picked up in Kathmandu. Antibiotics should of course be a last resort for treatment but my symptoms had persisted for a few days. I didn't need to take paracetamol for the mild headaches associated with the altitude, but we all seemed to have stuffy noses. Decongestants if used continuously can cause nose bleeds and I used locally sourced Tiger Balm, buying a small bowl and dissolving some in boiling water (the hotel rooms have kettles) to inhale each night before going to bed. We paid into a kitty and bottles of water were provided, so fluid intake was sufficient (as were the associated toilet stops). I bought dried fruit from a supermarket to help balance my diet.
Hygene - Do take plenty of hand gel (I got through 3 little bottles of it). I had packed a toilet roll, but I found the small packets of tissues that I bought in Kathmandu to be more convenient to carry. Many public toilets cost 1 or 2 Yuan to use, so make a collection of small notes when you can. I only used 2 little bottles of high factor sunscreen and a stick of lip balm, but our trip was in October. I never used my DEET as I only saw one mosquito.
Food - Breakfasts can be basic. Attempts to imitate western dishes deteriorated as we travelled further, so going Chinese was the easiest option in Tibet. Supermarkets offer an opportunity to supplement your diet. I regretted not taking some vitamin tablets with me.
Accommodation - At Rongbuk I needed and used my 4 season down sleeping bag, elsewhere in Tibet I just used my sleeping sheet, I also carried an inflatable pillow which I only used once and I used a 1 litre water bladder as a hot water bottle. The hostel at Rongbuk is somewhat rundown, cold and draughty and the smoke from the cooker chimney discouraged us from lingering in the only heated part of the building. The tented camp up the road may seem more comfortable, but the toilets there were dire. Some hotels struggled for hot water and the chamber maids at Zhangmu were the rudest I have ever encountered.
Travel - the Land Cruisers were not as roomy as I expected, but I had a collapsible daysack with me that I used as my 'cabin baggage' each day. The buses used were generally spacious enough.
Costs - I bought my Yuan in the UK (easy to do these days) and ended up taking too much, but then I didn't spend much on souvenirs (many are imported from India and Nepal anyway). Changing money in the banks in Tibet is very slow and bureaucratic, but the ATM seemed to work fine if you use the correct bank. The most expensive chapel to take photographs in was at Shigatze and cost Â£75 for still photos, but at other monasteries it was only Â£2 or less per chapel, so ask your local guide for advice on the best value photo opportunities. Meals in Tibet cost about Â£7 including one drink. GBP and US$ can be easily changed at the hotel in Kathmandu and can also be used a Delhi airport, although change is given in Indian rupees.
Reading material - we had no trouble with this on our trip. I took an e-reader with me for convenience.
