 Double check with the actual resort. Just because you're buying a timeshare, but potentially through a social media partner that seems legitimate, nothing is stopping you from calling them directly and saying, hey, do you really have this week available? Is this really who the owner is? Can you verify that before I do this, it's going to be correct? Or maybe call them directly and find out what they're charging. You might find that the prices are exactly the same or even better.
