In reply to mike123:
£1000/head grant is an inefficient way to do it. The coach or admin assistant block books all accommodation, travel, car hire for the group. It'll be way cheaper than done individually. Also style will vary according to country: hotel, hostel, house hire etc..depending on the sport, you could for example pay more for accommodation right next to the event and public / event transport, removing the need for van hire. Or the opposite. Catering, book somewhere with a small kitchen and save loads on restuarant bills. ... it simply needs an organised manager.
Edit. Many events have local affiliations so you can obtain specific discounts for certain hotels, van hire etc. Done in return for adverts within said sporting event. Again a good manager will know these already, as it'll be in event information.
