Yes, and unlike with II where SVO ("Starwood Vacation Ownership") often picks the week to deposit (even though it can only legally do that with SDO units that are within the SVN ("Starwood Vacation Network"), the week YOU book your SDO is the week SVO deposits into RCI, even if that SDO unit is in SVN.
(You can also deposit a prime SDO week (that YOU book) with SFX)
Good Luck!
