I'm not interested in taking your timeshare, but wanted to make a couple of suggestions, in the name of helping a buyer decide if they might want this:
Is the Week 26 fixed use every year in a specific unit, or does the Week or unit float? Checking the RCI website it shows two different resorts under this name - do you know which one it is? (High Sierra #1402 and High Sierra #DD61. Is there a difference, and is this ownership at one or the other of those?) Both are shown as RCI Points resorts - is this timeshare a Weeks ownership, or a Points ownership with an underlying deeded unit? You may have better success by finding these answers, and describing things very specifically, so a buyer will know what it is your'e offering.
I've had great success offering a timeshare for free if I agreed to pay the transfer fees for the new owner. It costs me a little more initially, but if it doesn't sell and new maintenance fees come due, I'm on the hook for that anyway. And maintenance fees are higher than the transfer fees would be. So it's money well spent. There is a Tug member, LT Transfers, (
http://www.lttransfers.com), that does timeshare transfers for very reasonable prices (like $150 or so for a simple transfer.) They are very professional, and are highly regarded. They can do the transfer for you, and save your buyer that extra cost. Make the offer enticing, and you'll have better luck finding a new owner.
(And if nothing else, have you contacted the resort to tell them of your parents' passing, and ask if they'll take a deed back of the ownership? If things haven't been transferred out of your parents' names, you don't have to accept the inheritance. You can have your attorney decline the inheritance, and the Resort HOA has to take back the timeshare. You can't be forced to accept it if you don't want it.)
BTW, it looks like a very nice timeshare.
Good luck!
