Generally, the process is after you say no to your sales rep the manager will come out. After you say no to that person a third person comes out for a survey. Currently, Lyndsay or Vida. Part of the survey is asking whether you still have any interest in buying a timeshare. At that point, if you express interest in buying you should be offered an Access package. It's their way of getting potential clients back. The Access packages do change from time to time. The last reported one that I saw was $3,094 ($2,999 plus $99 processing fee). You pay the $99 upfront via credit card and then the rest is auto-deducted monthly over multiple payments. This grants you:
a) locked-in pricing on the week/floor band/ float you are considering as of the day you sign the Access package until you return on your Access package (which is good for 2 years)
b) 5 nights in a 2-bedroom (they may have 1-bedroom access packages too for less - not sure)
c) 25K in WOH points OR a $250 resort credit.
Besides the $ paid, you are also agreeing to a 90-minute sales presentation when you return. If inventory on the EOY float week you are looking at seems like it is going to sell out you can always pay off your Access package early, and 100% of all payments made except the $99 processing fee can be applied towards the purchase of your new timeshare.
So, even if you were100% sold on buying from the developer, the Access package is still strongly recommended. By first signing up for the Access package before buying, you get the resort credit or WOH points PLUS an additional 6-night stay for basically $99 (since the rest is applied to to your purchase).
Keep in mind while the price is locked in the incentives aren't. Those vary by market conditions (for instance during the pandemic there were some stronger incentives). But, you would get whatever incentives are being offered when you did buy. If you really liked the current incentives, you might still get the Access package, then wait a bit, then call to confirm current incentives and then maybe purchase. They can then walk you through the steps, like paying off the Access package to apply it towards your purchase.
