They list this one as the Orlando 2-Park Getaway Package on UO's website. If you start the checkout process they have this link for early entry and it says:

*Requires theme park admission. Transportation is not provided to Early Park Admission. Offer valid 7 days a week for travel through 12/31/11. Only valid for Universal Parks & Resorts Vacations guests who purchase a complete vacation including hotel and theme park tickets. Standard operating hours and availability of specific attractions are subject to change without notice."
It wouldn't make or break my trip, but it would be super if DD and I could get into the park early. We are going only one day and only for WWoHP - anything else is gravy, but since I've never been to IoA it would be nice to make the most of the day there.
