There will be a streak of Eternal events that includes the only EU Legacy GP if anyone fancies spending some time over here.
4 Seasons Fall, 23th-24th Nov, Bologna, with both Eternal formats
Magicfest Bologna, 29th-1st Dec, the only Legacy GP in EU
Nebraska's War, 5th-8th Dec Lucca, with both Eternal formats

Bologna's got an international airport easy to fly to and takes 1h and half of high speed train to reach Venice in case one wants to visit it while using Bologna as base during the first week. Then 30mins by train to the south there is Florence that one has to go through and can visit for a couple of days on his way to Lucca. Close to the latter there is Pisa with int airport to fly back home.

If coming only for one week the best combination in terms of Magic, tourism and time/money saving is GP+Nebraska, visiting Florence in the meantime. I'm a local and usually friends come for Nebraska's War from overseas (Joe Brennan, Dan Miller, etc.) so I can provide information and lodging in Florence, do not hesitate to ask.
