Fwiw, my personal experience is that RedWeek is a great site on which to be on either side of a timeshare rental transaction.
That said, I would not encourage the use of RedWeek's so-called "Full Service" option, thereby subjecting (and limiting) yourself to their contract terms, their refund & cancellation policies and their owner payment schedule. In addition, the assigned "full service" agent may know little or nothing about the resort and be entirely unable to answer specific questions about it. Unless you truly want nothing at all to do with conducting and handling the rental yourself, I would pass on using the (so-called) "full service" option.
Personally, I much prefer to use a detailed and precise contract with terms and conditions of my own identification and also determine my own payment terms and cancellation / refund timelines. Those aspects aside, the "RedWeek Verified" option is (IMO) always worthwhile (for a mere $15 extra) to save you the time and aggravation of repeatedly having to "prove" the legitimacy of your ownership to nervous prospective tenants by instead "proving" your ownership and legitimacy just once --- to RedWeek.
Hope this helps. Good luck.
