On July 1st, Universal changed the Express rules for those staying at on-site hotels. You are now only allowed to ride each attraction once with your room key Express pass before 3PM. After 3PM you can ride as many times as you want. I was very upset when I found out about this yesterday and I'm sure many others will be too. I stay on-site almost every month for Express access and now they make this new rule without warning. The ride attendants did not seem to be enforcing the rule strictly but I didn't challenge it. Sorry to be the bearer of bad news.
