Hye .. we went on Costa Allegra last Easter .. round trip from Hong Kong [report posted on cruise critic] .. the key to passenger mix is the length of the proposed cruise .. if it's short you will be sharing with an overwhelming number of chinese .. if it's longer 10 days + you'll have a european / australian customer base .. it was an experience but not one we'd do again .. allan
