This is a solo travel forum for people who actually like the adventure of travelling on their own rather than the (IMHO) still greater adventure and risk of travelling with someone they have never met before.
Your sort of question/solicitation does, however, come up periodically and some very kind members of the forum have provided a thread answering the questions of how to reduce the risk:
I can't speak to how satisfactory the answers are as I have never been willing to risk my holiday in that way. I am happy to meet people on holiday and spend an evening or day with them, but the idea of agreeing to share my trip with someone who could be anything from simply a bore to someone who thinks a good way of transporting cannabis across an international border is by tucking it in my bag doesn't really appeal to me, but YMMV.
