Just want to make sure that you followed the rescission process exactly, and sent it certified, return receipt.
If you're still away, relax, enjoy the rest of your vacation and when you get home take the time to learn and understand your options. A few small comments- wrt the Getaways- not sure where they get the $99/year from- II membership is included with your annual DC dues which would be ~$175 for that number of points. As mentioned above, those Getaways are often good buys, and sometimes even great deals, but they are not free. And it's a perk of II membership, and available to any owner.
Wrt hybrid purchases- there are several different approaches- picking a week basically that exchanges for half the number of total points you want, picking a week that is a good trader for when you may opt to trade it as a week in II, and/or picking a week at a location and in a season that you might want to visit at least some years. So a good place to start might be to read through various threads here and get a feel for the different locations, and think about if there are any in particular that you foresee yourself wanting to repeatedly visit. If there is, owning a week at a particular location is likely the cheapest option, and you might even want to just buy a week on the resale market (the external resale market prices are cheaper, and in many cases MUCH cheaper, than through Marriott resales) to dip your toes in, so to speak, the least expensive way; if you're set on starting as a DC member, then that might be a week to consider as part of the hybrid packages bought from Marriott resales.
Before you do anything, make sure you understand all the different options and benefits as well as drawbacks of the different memberships, as well as not only the up front costs but also the annual MF's. The best place to start is by reading all the stickies at the top of this forum. And feel free to ask questions along the way.
