My wife and I treated ourselves to the F1 racing in Melbourne. Not being familiar with Melbourne we booked a package deal through a travel agent, which essentially was a company that takes groups to sporting events.
We calculated the cost of the package was twice what it would have cost had we flown to Melbourne, found our own accommodation, and bought the tickets to the event online via the F1 site (or bought them at the gate on the day). We met our group host once and after that he was totally invisible – which didn’t actually matter because getting to the venue was easy as.
