I think we got the message from your first post. Repeating it doesn't make your viewpoint any more compelling.

Perhaps you misread the OP's post but they said "I'm booked to go to Melbourne for 8-days." They didn't say they were thinking about it, planning it, thinking of including it in some longer trip or any variation thereof. It's booked (including the hotel). If you have some constructive suggestions as to what the OP might do in Melbourne (in addition to the Old Jail), by all means post that information. However, repeatedly slagging off Melbourne serves no useful purpose whatsoever, particularly when the OP's trip is already booked.
