It can be worse if they also play for local (non-school) sports teams. When I was in Sheffield the two main kids' clubs were always trying to outdo each other with their team tours. When one club announced a tour to Australia, the other immediately responded by announcing a tour to the West Indies. That was ON TOP of all of the school trips that parents had to pay for.
When I was teaching, I stopped running football tours abroad as most of the kids in the school teams couldn't afford to go on them. Instead we ran tours in the UK, using youth hostels, and every team member ALWAYS went on them (sometimes with financial assistance from the school). I'm sure that they enjoyed them just as much as going abroad.
(The only school trip I ever went on, when I was 14, was a walking tour of the Lake District. That was 2 years before my first ever family holiday, to the Isle of Wight).
