Also, Wikimania Takes Lake Como http://Programme/Wikimania%20Takes%20Lake%20Como (WTLC) is planned four days prior to 23rd (20th-23rd?). Does that mean folks who would like to attend this, needs to arrive on the 19th?
There is no "need", based on the description of the event (see talk page). But you may want to pay closer attention to the details specified on the page before asking more: in particular, it says that early arrivals are expected to have accommodation in Milan (indeed, that's the most logical place if you want to visit the region).
