Thanks! That's great to hear.
I just called to see if DVC had my reservation yet (confirmed Sunday), no luck as expected. I'm going to take a shot at breaking the RCI DVC unit code. Usually the pattern for other DVC resorts seems to be unit size, view type, check-in day of the week. So the unit on my confirmation is 288. Pretty sure the 2 is because it's a 2 bedroom.
The second 8 should be for view type. There are 4 view types, but they would need to separate out 2 bedroom lock-off vs dedicated. I don't think they would deposit a lock-off. So I'm guessing for lock-offs 1=standard, 2=island, 3=pool, 4=OV. For dedicated 5=standard, 6=island, 7=pool, 8=OV.
The third 8 should be for check-in day of the week. I have a Saturday check-in. This one stumped me, but maybe 7=Friday, 8=Saturday, 9=Sunday. And 1-6 they use for the 5 day rentals (I don't know what the possible check-in days are for those).
So there's my guess. Or maybe just wishful thinking that I have an OV unit.
For those who have/had RCI reservations, please let me know if this fits!
