I had inquired about a year ago and was also told they weren't available anymore. So our last trip we didn't bother asking. We had been over when they were offering it for free and loved our day there and considered going back. I still think the price is pretty steep. For a family of 4 we can do an excursion at that price. $100 a head is more reasonable.
I did love when we offered it for free, as it really is a beautiful setting that we want to share with as many people as possible. Unfortunately, it was the case of a few bad apples ruining something really cool for everyone as several of our homeowners and resort guests had really unfortunate experiences on a few different occasions.
After that, we decided to charge for them and then subsequently increased the price with the main goal of ensuring our homeowner and resort rental guests experience there
