I think many of us assume that because it would be more trouble than we think it's worth to do an illegal pool hop, or park at DTD to get free parking that no one else would do it. But, I think there are a lot of people who just want to find a way to 'beat the system.' I would never waste my valuable vacation time to save a few dollars, but I know everyone is different.
The two times I have been at SSR I didn't find the pools or buses to be overcrowded, although that doesn't mean there's no impact. I do think that our dues would be impacted by people who elect to use SSR services they aren't entitled to. At some point, the extra people on the bus will impact fuel usage, and might create a need for more buses. If people use pool towels, that will affect laundry or housekeeping fees.
But I think one more thing needs to be addressed, and that would be the lack of security that is demonstrated here. So, anyone can just walk or boat over to SSR from DTD or the DTD hotels and use SSR services. I am equally concerned about the security issues this raises. I think that this can be mostly remedied by a requirement to show a KTTW card at the pools and when getting on the buses. Additionally, the walking paths to DTD should have a gate with key card access (like the gate to the beach at VB). I think these minor adjustments would take care of most issues related to mooching and security.
