New health code or a scam?

Friends of ours were in Vegas last week staying at Tahiti Village time-share (I believe they also have rentals). They could not bring any food or drink (including snacks, water, etc.) into the pool area. They were told they had to be purchased on the premises and they sighted a health code. They searched their bags every time they came in. This had not previously happened to them. Anyone having problems like this at any of the hotel pools?
I would not be surprised if it is an actual code. I have seen signs that state the same thing on several different pool facilities in town.
Thanks for the input. Really appreciate it !!!
Anytime....wish I could be more help!

We actually own at Tahiti village and yes, this is new, we were never searched in the past. Tahiti Village posted this information in an owner's newsletter last year.
I see....thanks for the update deniahl....
