If you are going to call each day, to add a day, I"ve found the process works best if I tell the Member Services rep on the first call that I want to make a multi-day reservation and will be calling each day to add on. That way they somehow set the whole reservation detail up in the record with my preferences and don't treat it as a stream of separate one day reservations. This means that I only get one confirmation number, one written confirmation after I've made the last days call, and have a very easy process when I make the daily call.
