To cover the costs of a local coordinator, we include a budget of £50 for him/her. This is valid if 40+ persons are brought to a 3-day trip through that coordinator, from any source.
We also now have London guides to optionally handle the more complex Sunday tour of London with commentary. If you are the local coordinator who chooses one of these trips, and you are willing to handle the other 2 days yourself (mainly just getting to the hotel and back home again, using our London-savvy driver), you can have a totally free place yourself.
Also, up to 6 regular pioneers can usually travel for a subsidised £99 fare (excluding any add-ons such as London Eye, etc), subject to our checking of the costs of the trip with your local coordinator. (Derek is also a regular pioneer). If your coordinator is also a regular pioneer, this applies also to him/her.
Why not ask your congregation if they will also sponsor the pioneers? They are your full-time ministers, without pay! It is a very appropriate theocratic event for them.
Other discounts and incentives are available for collecting 10 or more names for any trip, including foreign Bethel trips.
