It has nothing to do with the hurricane, imho. Many resorts had only minimal cosmetic issues (tree limbs in pools), others had slightly more issues (limbs down, sand in pools & elevator shafts, etc), and some had moderate+ issues like water in units necessitating repair/replacement. Only a few suffered more catastrophic damage like major trees down, destruction of buildings--- like Royal Dunes. Those had "downbursts" (small dipping/skipping along of tornadoes hitting erratically). For the most part, the major resorts had very little damage....such as Grande Ocean, Barony, Surfwatch, etc along the oceanfront (minimal debris clean-up, exterior painting, sand removal, some unit repairs, etc.) I believe nearly 100% of clean-up & repairs were completed months ago. Islandwide, in the more heavily forested areas, there are still large trees down, with an ongoing effort to cut them, stack them, and slowly remove them in an organized fashion. I've noticed a lot of that as one drives farther onto the island after the bridge. Practically speaking, those areas are only cosmetic to tourists, altho environmentally they are more severe......i.e., it doesn't affect the tourism directly.
To the OP's dilemma, I believe it's a couple of things: oversupply and people waiting longer to get a deal.
There's a definite glut of rental units this year. Speculation, but it could be that rental fees have gone up dramatically in recent years, and owners are wanting to reap the benefits. There is a history of high demand for summer HH units, and recently, more demand for any season, even so-called "off-season" (but that term may soon no longer apply to HH, as many resorts are near capacity in Jan/Feb.
Grande Ocean particularly has a lot more listings this year than normal, especially summer weeks, with high fees. Whether or not they're getting renters at the high fees is another story. If all rentals are down dramatically across the board, or we start to see even the lowered fees drawing no interest, one could blame the economy. Not so sure I'm seeing that yet.
Many renters (I've noticed in last 2-3 years) are waiting longer to book anything. Lucky for me, but I listed two June weeks for rent at Grande Ocean back in January only due to scheduling conflicts of our kids who couldn't come---one rented within 24 hours, another 2 weeks later.
We will still be using 3 consecutive June weeks, in spite of letting two reluctantly go to rental.
I also listed a Myrtle Beach non-Marriott week for June, and it just rented this past week, 2 weeks before check-in and at a very low fee. Some of the higher-rated resorts have very high listing fees, and I'm not sure renters want to pay that much, so again, many seem to be waiting. Some don't, though, and make early commitments, but overall I think many are waiting.
OP, be patient, you may still get a renter if you hang on, but fee must definitely be near the bottom of the listed fees to attract a renter, no matter when that time is...in January or now. If in the middle of the pack, the lower fees will go first ahead of you, always,
and you may have to make a move. Avoid the inevitable, reduce it now. You'll end up at the same number, only earlier. I've always felt one should have a reasonable fee (somewhat near the bottom of listed fees) in January/Feb to get an early commitment on a summer week.
Also, it ALWAYS depends on the resort too. The lesser resorts don't seem to move as quickly as the nicer, larger, oceanfront ones.
