I don't believe there are any restrictions other than the restrictions on glass containers.
Last trip to HHI we had an awesome villa, 1st floor, overlooking the pool, right by the entry gate to the pool. We brought out lunch, sodas and beers every day, as well as snacks. Sometimes, if someone was inside, the kids would call up and we'd pass down drinks and snacks to them from the balcony.
Have a great trip, I love HHI, we never had a bad trip there- even considering my intense fear of Palmetto bugs, lol.
