Hi Jewell!
Rainforest Cafe is a participating restaurant on the 2019
Disney Dining Plan. My family ate in the Rainforest just last Friday evening while on the
Deluxe Dining Plan. I did take a look at the
2020 Disney Dining Plan participating restaurants list and none of the Table-Service restaurants at
Disney Springs or at
Disney's Animal Kingdom are on the list...yet. There has been a previous trend of non-Disney owned and operated restaurants taking a little longer to be added to the participating list than Disney owned and operated restaurants. Even though it says they do not participate right now doesn't mean that they won't participate at all. I can't imagine that guests won't be able to use their Disney Dining Plan meal entitlements at any of the Disney Springs of Animal Kingdom Table-Service restaurants next year, but you never know! Plus, Rainforest Cafe has been part of the Disney Dining Plan for a handful of years now.
My suggestion for now is to keep your Rainforest Cafe reservation and make yourself a back-up plan just in case they aren't added to the list. Even though you're only four months away from your vacation, that's still plenty of time for changes to be made to the participating list. I'll be crossing my fingers for you and sending pixie dust your way. Rainforest Cafe is such a great restaurant!
Please stop back by and visit if you have any additional vacation planning questions.
Have a magical day!
