You may reserve vacations at your home resort 13 months ahead of travel. At the rest of the resorts, it's 10 months ahead of travel. So, if you plan to repeatedly stay at a very popular beach resort during the summer break from school, you would want to own at that resort for the early booking advantage. If not, and you plan to visit many different places, then home resort matters much, much less. Oh, and I think there is an advantage to owning (for some people) in Hawaii, if you want to be part of the Outrigger Club. But I don't know much about that since we don't travel there.
Also, your maintenance fees are based on your home resort. Some are much higher than others. Look for something around $3.00/thousand points, including FairShare Plus fee and annual taxes (which are included in most places but billed separately in Florida resorts).
Nightly stays go by a basic set of rules, which are pretty much the same, system-wide. During "prime" season, you may book 3-night, 4-night and 7-night stays, up until 3 months before check-in. Then nightly stays of any length are fine. These 3- and 4-night prime season reservations are supposed to either begin or end on a typical check-in day at the resort (usually Fri/Sat/Sun). There are exceptions to these restrictions with certain resorts.
For reservations in High, Value or Quiet seasons, you may reserve nightly stays for 2 or more nights, any check-in day, whenever you are within the booking window. At 3 months before check-in, single nights may be booked. It's all pending availability, of course.
The advantages to Gold VIP are mostly related to eliminating some added fees that most people pay if they tend to book many short stays and/or send a lot of guests in their place. There is a slight (1 month?) booking advantage on a limited number of reservations with Gold too. But to get it, you would have to purchase all of your points (500,000) from the developer. Most people save tens of thousands on that size purchase by going with resales so paying an occasional nominal fee, as needed, is not an issue worthy of seeking Gold VIP.
I think there are still a couple of resorts which are closed due to hurricane damage in Pompano Beach FL and New Orleans LA - they may not be the best buy due to assessments and lack of access, though some people may see them as a potential bargain. Other than that, you may simply prefer a particular home resort because it's where you want to travel the most during prime season, because it's got a relatively low maintenance fee, because you love the place or because it's close by and you prefer owning near home. We've owned in New Bern NC for many years and haven't yet been there. HTH.
