Nothing is more restful than a lazy hour swinging under a palm tree. I know you can find hammocks on the beach at the Poly and around Coronado Springs...anywhere else? Any of the DVC resorts? (We're staying at OKW later this summer...)
Definitely at HHI, don't know about Vero. A couple years ago, they were gone from HHI and I was concerned. But last fall they were back-the CMs told me that they'd been ruined by the weather, so had to be replaced. Of course, I tested out these new ones just to make sure they were OK!
They used to have them at FW on their beach. We would go over to eat at Trails End every few trips and they were always out. Our boys loved to get in them. However the last time we went.....in the past year....they were not up. HOWEVER it had been raining so we equated it to that.
