I think you're much interested in meeting up with other bitcoiners around the world at the cause of your tour on each country you planned to visit, but have you also consider the privacy from your end and that in which others may want to secure by the way of having interactions with you, though am not saying that you're likely not to see any interested to have you come along, but the fact is that there is still a level of personal identity many would love to preserve, instead you may consider the use of an exchange for this and use fiat in running all the local errands you may demand at the cause, be also careful of those that may try to impersonate others from this forum just to take advantage or scam you.
