You'll have better luck learning if you log into their RCI account, so you can see things "live." They probably have an account, but there is a subscription cost.
Once logged in, you can check the details on what they own (by finding the resort name in their library.) If they have a fixed week or unit, you can then easily see the value of TPU's that RCI will give you by checking the Deposit Calculator. If the unit or week float, you can play the system a bit, by checking different weeks or unit types to see which gets you the most TPUs for a deposit. The TPU values are lower, the closer you are to the checkin date at the resort. They're higher for holiday weeks, and more desirable times. Christmas or New Years weeks often get the highest TPU values of the year for an exchange. If you're at least twelve months out, the full TPU value would be given for a deposit.
To make an exchange, you need to actually deposit the week to receive the TPU credits in your account. And once you know the TPU value of the deposit, you can look to see what is in the RCI system that is directly available to exchange. If you have enough TPUs available, you make the exchange, pay the exchange fees, and it's a done deal. If you don't have enough TPUs, you're pretty much out of luck, unless you want to make another deposit, and combine the TPUs together. (That's a whole different topic.)
If the resort you're seeking is not available at the time to exchange, (which is very likely - the available exchanges are the leftovers) you can do an Ongoing Search (OGS) to place yourself on a waitlist for when the week and resort you want becomes available. If/when it is deposited by someone, it matches your OGS, and you have the option of accepting the exchange. There is no guarantee the request will ever come in, so you need to be pretty flexible on what you'll accept.
Once you decide whether RCI will work for you, explore other exchange companies. SFX, DAE, Platinum, and others are out there. They may give you something better than RCI if you deposit the week with them instead. They all work a bit differently, and they each have their own learning curve. You do not have to deposit only with RCI - the alternate exchange companies are nice, each in their own way.
Hope this helps a bit. Good luck!
