Usually you exchange your week for a week at the chosen resort, pay the exchange fee, then you must pay the All Inclusive fee to the resort which RCI has plainly stated on the website and I believe on another pop-up right before you book. I often see that fee at, or over, $100. / day / person. There may also be a resort fee on top of that. In our over 43 years of RCI membership I have never found an All Inclusive exchange that was cheaper than what I can book online or even with a travel agent that also included airfare from Toronto and a shuttle to the resort which you dont get by going through RCI. We always use RCI for regular timeshare vacations and book any AI stays on our own online. If you use the filters on the left side of the RCI website when looking for a resort, there is one that you can choose AI not required. That will filter out the mandatory AI resorts. Look carefully at the resorts before booking as many will not have a kitchen and you will need to take a cab or resort shuttle ($) to get groceries or go into town to eat, and also may be limited to what onsite restaurants you can use. I even heard of one that limited non-AI stay people to what pool they could use.
