Just get in touch with the club if you're having problems with the tickets.
If you notice, the original fixtures are always scheduled on Sunday, then moved. Easter weekend they're originally scheduled for the Saturday. Everything will be open Saturday. Sunday there's a big Easter parade in the city centre that's worth seeing. The further out of the city you go on Sunday, the more chance there is if things being closed. You won't starve though, as bars and restaurants will be open. Monday is a holiday and almost everywhere will be shut.
Just let me know if you want any tips on being in Milan.
