  booking_type = BookingType.first(:name_permalink => params[:booking_type], 
                                   :boat_type      => params[:boat_type])

Then I use a single controller for all the bookings as the actions are common.  i.e. if a dinghy 
booking type with :name => regatta is added, the url /admin/dinghy/regattas is valid and rotes to
the admin/boat_bookings controller (etc etc for other booking types and for yacht bookings).

...and I actually only wrote this yesterday so haven't yet found out if I can do this in a 
'resources' type way to save me adding each of the restful routes in turn - it'll be _really_ be
sweet if I could :)

So far it seems to be working very nicely - the url(:admin_boat_bookings) constructs are working 
like a dream.
