[Rails] Rails way of constructing an url with post parameters of a form

I would like to do that's the best way of actually accomplishing the
following on Rails.

I have a "Booking Form" with 5 fields (Property, Amount of Children,
Amount of Adults and 2 Dates - Departure and Arrival) based on these
fields, I need to construct an URL and redirect the user to this url.
Now, I have 2 questions.

1) How i catch the POST parameters in the controller, because I'm
mapping the form to an action like this:

<% form_tag(:action => "booking") do %>

and routing it to a controller action like this: (Pages Controller,
Booking Action)

match 'pages/booking' => 'pages#booking'

2) Is this the Rails way of actually accomplishing such thing?

I did it this way in PHP in the past, but now I have the need of
actually doing it in Rails, could you Rails Gurus inspire me ?
