Just returned from LCA (on the other deal, though), and I would recommend checking out the deals offered by German charter carrier Condor. We paid EUR 29.00 all in for LCA-MUC, and the same fare would have been available for FCO-MUC. They have special 48-hr sales once a month (the next one is due to start in about 20 hours). You could then either stay in Germany/Austria/Northern Italy/etc., or book another Condor deal to various European/International destinations for EUR 9.00/29.00/99.00 all in each way.
