Once you have set up your account you can spend some time exploring the
DVC website to become familiar with how it works. Typically you will use the website to book your vacation, when you enter your desired vacation dates/resorts in the plan a vacation tab a calendar will load showing what is available for booking - on the disboards we call this the RAT (resort availability tool.)
As mentioned, you can book your home resort -SSR in your case- 11 months before your planned vacation. If you fancy a stay elsewhere (like say, the Poly or VGF) you can book wherever else you want to stay 7 months before your planned vacation. Many people book their home resort (SSR for you) at 11 months then switch to their desired resort at 7 months, that way they have a place to stay if everything is booked elsewhere. SSR is relatively easy to book compared to some other resorts. Because of all the canceled vacations last year it will be harder than usual to get reservations, especially at 7 months for popular times and resorts, in the next year or two because all of those extra points that need to work through the system.
What is your use year? Your use year month is when your points ‘reload.’ Use year does not effect when you can book and has nothing to do w/ the 11/7 month booking window. It does effect which points can be used for a particular vacation. For example, I have a December use year, my current use year points are 2020 points and can be used for vacations occurring between 12/1/20 and 11/30/21. If I had a February use year my current use year points would be 2021 points which could be used on vacations occurring between 2/1/21 and 1/31/22.
If you have a year where you aren’t going to use all of that year’s points you can ‘bank’ them to be used for a vacation in the following use year. The important thing is that if you plan to bank, you must do so in the first 8 months of your use year. For my Dec. use year that’s by the end of July, for a Feb. use year that’s by the end of Sept.. In my case, I booked a trip for Dec. 2021 right at 11 months (January of this year) and banked the points & immediately used those just banked 2020 points for that trip.
If you want a vacation that ‘costs’ more points than current use year points + any banked points saved from last year, then you can borrow from next year’s points. In the past you could borrow all of next years points if needed, right now you can borrow 1/2 of next years points.
You have the option of setting up a monthly payment plan to pay your maintenance fees, many prefer that as it can be a bit of a financial hit to pay those dues all at once right after the holidays (they’re late if not paid by Feb.).
I think that since your contract is a gratuitous transfer and the original owners were probably blue card members you probably will be as well, which entitles you to DVC discounts, entry in members events, use of the lounges, and booking the Riviera - hopefully someone else will confirm this.
Oh, and if you’re a big Disney fan, what a wonderful gift, I hope you enjoy many great vacations in the future.
