SFX still charges the $75 flat fee but for Grand Luxxe don't they charge another $299 fee to exchange in on top of the regular exchange fee.
I think it is in recognition that the Luxxe units especially the 2-4 bedroom ones in both SFX and II are developer deposits not owner deposits. II still has the 12 per person per day but RCI now has the higher per person per day and it applies to children 6-12 ( I think as well). In the past and I don't know if this is still the case, Luxxe deposits listed under platinum priority were excess Registry collection deposits and had no extra fee associated with them. In terms of straight RCI deposits, I don't think it is an option for Luxxe owners so non registry inventory even the smaller units would be excess developer inventory. Vidant has so many units resort wide through all the levels. Looking at the number of deposits the various exchange companies get, my guess would be in the 6,000-10,000 units per year range with the majority of these either being developer deposits and the owner deposits often being owners exchanging back into the resort.
IMO - Vidanta likely does developer "deposits" the way hotels and airlines list on travel sites . ie The same week is listed on more than one exchange company . As bookings come in they
update the listings . Call it "floating deposits" for a RTU float week system .
They also have to hold back enough inventory for their major ARP points in owner contracts (1 year / 6 months) before snowbird months .
My Mayan Palace contract has 6 month ARP - so Aug. 1 2018 I can book any Feb 2019 week ( using my 2018 registered owner week) . Aug 1 is a very busy day at their Neuvo Vallarta call centre .
Since Vidanta builds in pesos and collects MF in USD - they have built for peak snowbird season ; and have lots of shoulder season availability

FYI - I think there is a lower $ exchanger fee for children .
It is worth looking at the total cost of an exchange / not just the resort fee . For example :
Grand Mayan NV - 2 bedroom - April, May,June 2018 - 8 TPU's - RCI Weeks .
If your TPU cost is around $20 ; that is about $1300 for 4 ( TPU cost + RCI exchange fee + resort fee x 4 )
-in a spacious 2 bedroom , with full daily housekeeping and towel service, AND $ 210 (25% of resort fee) is credited back for restaurant etc use at the resort .
Assuming you eat -
$1090 - Net for the week .
******
FYI - they will bill the resort fee in pesos ( based on their daily posted USD - peso exchange rate )
this helps Canadians and others by not having to pay to convert twice via a credit card
ie Mx pesos to USD to $ CAD = xx / is likely more costly than Mx pesos to $CAD .
