Tour companies are ripping families off and nobody is calling it out

We got quotes from three tour companies for a Gothia trip. Range: $2,800 to $5,200 per player. Same tournament, same dates, roughly same accommodation quality. When I asked the expensive company to justify the price difference they couldn't. The markup on these trips is obscene. Clubs should be booking directly — flights, accommodation, ground transport — and saving families $1,500+ per player. Why don't they?
