Newbie questions

Another question I just thought of is can I make multiple future reservations for more points than I will actually have at the time of travel and then cancel the ones I'm not going to be able to go to later? The reason i ask is because I don't know what days off i am going to be approved for my work until the end of the year every year for the next hear. So would I be able to make let's say a 2 week long reservation at the Riviera for may 2026 and a 2 week long reservation at Animal Kingdom for September 2026 this year and depending on what days off my work gives me, cancel the one I can't go to without penalty? Will the system allow me to book multiple reservations even though i would be going over all of the points i could possibly have? 🤔 I really appreciate all of the people that have responded to me as this is very confusing for this newbie!
