Add me to the list of members who like receiving email confirmations. We just booked our trip for October 2011 and we received the confirmation email about an hour after we got off the phone from talking to MS.
I also like the fact that a single confirmation email covers the entire stay even if split stays are involved, and even if different guests are staying on different days. In June 2011 we have a family gathering that includes my sister's family. The email confirmation shows all 6 of us staying at AKV in a 2-bedroom for 5 days, and then its shows that my wife and I move to a studio at VWL for the last 4 days.
By the way, the CM at MS gave us a choice of receiving the confirmation by email or by regular mail. So if anyone prefers to receive a paper copy in the mail, we still have that choice.
