I have deposited my 2 bedroom Marriott Canyon Villas week into Interval via a Marriott phone rep and received an Interval Accomodiation Certificate. The same happened when I deposited my KoOlina week. My question--is there any "rule" as to if/when you receive an extra week via the Accomodiation Certificate when depositing? I have never deposited a week online at the Interval website, I have always done it on the phone with a Marriott rep--they have been the ones who got the certificate. Exactly what is the criteria for whether you get this bonus week or not--or do I get it every time I deposit a Marriottt week? I typically will deposit the Canyon Villas week for trading, but would like to get the Certificate if possible. Thanks in advance!
