Once again a time share rental that you can instant book, your money will be taken, but there is really no availability. They try and get you to book with them on different dates in different units but you can't because your vacation is set. On top of that, your thousands of dollars will take 2 weeks to go back to your account and you may not be able to book anything else and your vacation will be ruined.
Hard pass on any of this person's listings in future
