We could not find a way around the 90 day limit in the Schengen zone. Our original plan was also for 4 months, but 3 months ended up working well for us anyway. We thought about trying to get a visa for a longer stay in one of the countries, Norway, but that turned into a real fiasco. If you can get a 4 month visa in the country you enter and leave Europe from, it should not matter where you travel to during that period. I'm not sure that will work, because we were not successful in getting a long-term visa. It seems that the countries we tried to get a long-term visa from were reluctant to give them for "holidays".garthb
One question that I'm now somewhat concerned about--the Schengen area only allows for 90 days of travel within a 6 month period, i.e., I couldn't just exit and re-enter the next day. To those of you who have done longer trips in the zone, how did you bypass this requirement? I can't find anything from googling about it
I am also curious if anyone has been successful. Good luck.
