onward to tibet

ok so here is the low down. landin in nepal on the 19th oct and doin the ebc trek straight away. its a pore booked trek for charity. after that i have 3 weeks b4 i fly hme. i want to go up into tibet. i plan to fly in and drive out via ebc on the tibet side. or vice versa. have looked at the trekers society and green hills tours etc. im travelling solo just so ye all no. my worry is how easy will it be for me to rock up to the green hill office or any other office in thamel and get onto a tour with a few others. will the company jst fit me on a pooled type tour with other agencies. i dont mind once i get on a tour
all info greatly accepted
happy travelling

Just check it out when you get to Kathmandu, there are travel agents all over Thamel. It should be easy. It would be best to try to arrange it before your trek so they have time to schedule you in.

#2 is as hard to understand as the OP. Pretty sure #2 isnt Irish but a spamvertiser.
