I think he means that he wants to pass a variable rather than
the literal string "The_value."
Alexander, you just need a string argument to RESPONSE.redirect. 
Everythin in double-quotes above is a python expression, and it's easy to 
built a string out of variables in python.  You can use the + operator
to concatenate strings, or use the % operator to do printf-style formatting.
An example of the latter, assuming the variables are available in REQUEST:

 <dtml-var 
  expr="RESPONSE.redirect('Disponibilidad?Arrival=%s&Departure=%s' % (REQUEST['start_date'], REQUEST['end_date']))">
