I just found the website for TLC Resorts Vacation Club. How do they differ from a TS? Other than you don't own anything?
Another important way they differ is that there may be a very specific (and very limited) number of resorts at which reservations can be made --- and the available inventory at those limited number of resorts could also be very limited.
Last but not least, "vacation clubs" can (and do) sometimes just suddenly disappear into thin air, along with any and all paid "memberships" and any and all future reservation options or opportunities for those paid "members" left holding the bag.
I do not claim to know anything whatsoever about "TLC Resorts" or their reliability or solvency, but I fail to comprehend (or believe for one moment) how $300-$600 dollars per year in fees could possibly provide 6 weeks of vacation
anywhere.
I would definitely file that particular assertion in the category of "too good to be true".
