How busy have they been lately? I know I've seen less parasailers than I normally do, but can't say I've been looking for them so could just be they were still there and I didn't see them.
Water skiing, I saw a few of last time I rented the little boats.
I'd assume it's related to the gator incident, but I feel like we would've had more notice if it was the contract expiring and Disney not renewing. And if Disney was pushing them out for that reason, it would've happened closer to the incident. So not enough interest would be my main guess. But I don't stay in those hotels so maybe it's busier than I've seen.
