Rails - Feb 2008 - has many through: Users, Reservations, and the zen of being totally confused

Hey folks,
  This is a question about my rails app. It takes online reservations
for a hotel. I''ve got a has many through relationship all set up and
working:

class User < ActiveRecord::Base
  has_many :reservations
  has_many :events, :through => :reservations
end

class Event < ActiveRecord::Base
  has_many :users, :through => :reservations
end

class Reservation < ActiveRecord::Base
  belongs_to :user
  belongs_to :event
end

My confusion comes when I try to actually manipulate this data. In the
view, how do I show what users are linked to an event? How do I put a
list of users in the event/show? Am I drunk enough to be this
confused?! Can some brave soul shed light on this hairy-est of
queries?

Mahalos.

Well,

if event is an Event, then

event.users is the collection of its Users
