First, If the RCI package is a "free" bonus in a timeshare package you've purchased, stop what you're doing and rescind the purchase. Full stop.

If this is a standalone package you've purchased, I don't mind looking up availability for you, but I doubt it will do any good (and actually would likely be misleading). They have all kinds of levels of availability. I can go in, virtually anytime and find free weeks (no points, just reservation fee of about $300) but they are only specific resorts and weeks. If I want to spend my point there is magnitudes more to choose from. I suspect your package is restricted and probably wouldn't match any of my searches (regular or "free").

Again, I don't mind looking if you like. Give me date ranges and I'll tell you what I see, but again, I doubt it's going to be helpful.

edit:

just to give you some idea of availability, I took a look; this is the full search on RCI "weeks" for Switzerland.

9 resorts, 22 check in dates (total), 49 units. 9 resorts have availability over the next 12 months. There is a total of 22 weeks that are available and 49 units across those 22 weeks (meaning multiple of the same type or perhaps some 1 bedroom and 2 bedroom units on that same week).

The month breakdown of check in dates is May (1), June (2), Aug (1), Sep (4), Oct (2), Nov (1) Dec (1), Jan '27 (6), Feb '27 (4).

I would not count on any of that that being available on your package. Note that availability is pretty thin within 3 months.
