Hello all. I have a plan to visit Europe this fall, winter, and spring; hopefully volunteering through Helpx. I was hoping to visit Portugal, Spain, France, Italy, and Greece over 5 months but it seems these are all schengen countries and apparently the limit may be 90 days for tourists. I'm from the United States so I don't think I need a visa to visit for these 90 days but it could cut my trip short by two months, or I'd have to go somewhere else before coming back.
Also, does anyone have experience working for cash or making money while helpxing or wwoofing? Hopefully not too off topic but it's interesting nonetheless. 20 or 30 hours per week still leaves plenty of time to do more, if I'm not in the mood to do my own thing.
Does anyone have experience crossing borders, particularly schengen countries, to do these activities? Do you just lie and say you're a tourist? Or do you tell them you're volunteering/workiing? Do you need a "work" visa to do volunteer work? I'm checking the web sites I can find but so far have found no clear answers.
