Hi there, Meredith! Thanks for your question!
I'm so glad to hear that you will be staying at
Disney's Paradise Pier Hotel during your upcoming trip! You will have an absolutely delightful time at this beach-themed hotel, but, unfortunately, there is no private entrance for Disney's Paradise Pier Hotel guests into Disney California Adventure Park. A very long time ago, there was a special entrance option, but it has since been closed. There is also a park entrance from Disney's Grand Californian Hotel and Spa, but that is only for guests of that hotel.
Luckily, it is just a short walk from your hotel to the parks! In about 10 minutes, you can be at the park gates. The best way to get to the parks is to exit out the back door at Disney's Paradise Pier Hotel. You'll then turn right and make your way toward the Disneyland Hotel. You'll encounter a security checkpoint and then head on down through the
Downtown Disney District to the parks. It is easy peasy!
I hope this helps. Have a fabulous time at the Happiest Place on Earth!
