Hi Gregg!
Thanks for stopping by with your question! It's quite a popular question being asked by Guests right now, as people are planning their fall Walt Disney World Resort vacations.
Rivers of Light has been very popular with Guests, and the Rivers of Light Dining Package is an awesome way to experience it. Guests who reserve the dining package enjoy a delicious dinner at one of two select Animal Kingdom restaurants, then receive a voucher for premium seating for the show.
Unfortunately, we don't have access to information about when future dates may become available. I encourage you to keep an eye on the
Rivers of Light Dining Package page for additional dates to be added to the calendar. What I've done in the past, when waiting for dates to open up for a dining event, is set an alarm on my phone at the same time each day to remind me to check the Walt Disney World Resort website! Other great sources of the most up-to-date Walt Disney World Resort theme park information are the
Disney Parks Blog or
Walt Disney World on Twitter.
What you may want to do is go ahead and make a dining reservation for Tusker House for the day you're planning to visit Animal Kingdom. Once your FastPass+ reservation window opens, you can then make a FP+ reservation for Rivers of Light on that evening. If Rivers of Light dining packages become available, you can always secure one at that time, and cancel your prior reservations (you won't be able to add the dining package to existing reservations).
I hope this helps. Have a magical day! - Diane W.
