No, it must be a resort key from one of the Universal resorts, either the Royal Pacific Resort, the Hard Rock Hotel, or the Portofino Bay Hotel. We went to US for the first time earlier this week, and I have to say that when the parks were busy, which was every day except Sunday, those room keys were worth their weight in gold. For example, on Wednesday it was unbelievably hot and my girls and I basically walked onto a water ride twice in a row while persons without the hotel cards stood in a line with a posted wait time of 110 minutes. We saw so much more of the parks than we would have otherwise.
