Thanks. I have red on TUG that while the exchange fee is lower, they inflate the points needed from DRI resorts to make the exchange. I don't have any personal experience on that.
@NiteMaire and DRI weeks owners with good and relatively affordable weeks seem to do well trading weeks.
Yes, deeded weeks can do very well in DeX. This morning, I exchanged for a July 4th week on the Big Island. When I get the email, I'm sure it'll have RCI on it, just like my exchange into The Grand Islander by HGVC.
On the deeded side, we pay a tier upgrade fee to get access to certain inventory. For instance, we paid $149 for the trade, then an upgrade fee of $225. Not a bad deal considering my cost basis is ~$475 for MF. I could have avoided the additional $225 fee if I selected the 1BR since it would have been the same tier as the Sedona unit I deposited. My exchange cost would have been only $149. Room size, view, and season seem to be the driving factors (among others) for DRI unit tiers. I'm not certain what is used for the inventory pulled from RCI, but some of those apply. For instance HGVC, Shell, and Wyndham 2BR units in Hawaii are all tier 5 (for the time frame I was looking at). My 1BR at Sedona Summit is tier 4, while the studio is tier 3. If I deposited the full 2BR (which I will never do), then it would be a tier 5 as well. One great thing about DeX is that I can choose the view if it is a DRI resort. For instance, 2BR at Point at Poipu can be tier 4 (garden/partial ocean view), 5 (ocean view), or 6 (ocean front). For certain weeks the tier is one higher (except tier 6 stays tier 6). If I want to minimize cost, I'd select a tier 4 unit and use my tier 4 Sedona deposit. If it's not a DRI resort, I'm subject to whatever view is associated with the RCI exchange.
@escanoe reference one of your previous posts, there is HGVC inventory in DeX; however, it's through the RCI affiliation, not the acquisition. It's very limited, but it's there. We'll see if (slightly) more inventory is available in the future.
I recently used II to exchange into Ka'anapali Beach Club. Cost was roughly the same as doing it through DeX, but I purchased ePlus and have flexibility to retrade if our plans change. I've mentioned other places, but DRI has a draconian cancellation policy. While you can pay $75 to avoid the full $200 to reinstate your deposit, you still lose the exchange fee and any applicable tier upgrade fee. Ouch.
