Hiya Kamryn!
Welcome to planDisney! My friend, the excitement must be palpable in your home. You will be visiting Walt Disney World Resort very soon! This is wonderful news and I hope that you have a great time as this is a wonderful time of year to visit!
Early Theme Park Entry is a benefit for guests staying at Walt Disney World Resort Hotels and a few other select hotels. The list for the "Other Select Hotels" can fluctuate but right now the only Holiday Inn that has this benefit is the Holiday Inn Orlando which I believe is the one near Disney Springs. Unfortunately, it does not appear that the Holiday Inn Express and Suites in Orlando-Lake Buena Vista is eligible for early theme park entry.
Now, don't let this deter you from a good Park strategy by arriving at least 30 minutes before the
regular Park opening time. Magic Kingdom Park has a few sections of the Park that only open up with regular Park opening time. Liberty Square, Frontierland, and Adventureland are roped off until the regular Park opening time. This means that it's a smart idea to head to these areas when you arrive and be one of the first to enjoy
Big Thunder Mountain Railroad,
Pirates of the Caribbean, and
Jungle Cruise. At Disney's Animal Kingdom Theme Park, your focus should be on getting to
Kilimanjaro Safaris which is fabulous to do early in the morning.
I hope you still have a magical time!
Happy Planning!
