Yes, go to guest services. We had this for our trip as well. We had two extras with a code to activate them at guest services (given to us pre-covid), but we used them in Jan of this year. It was more beneficial to have them now more than ever, so go ask nicely, and they still might add them now (they did for us). The only problem was that I was told that which ever park you are in at guest services is the only park they can assign them in, so if I wanted my two split between two parks, I had to stop at two different guest services. I decided not to push my luck and just took two bonus FP in the park I was in (EP). But I mention that to you in case you already have ones in mind you want to use it on. If I knew this ahead of time, I would have changed my park that I went to guest services, I was in EP, so I picked Frozen and Test Track, but if I knew about the park limit ahead of time, I would have stopped at guest services in HS instead. And they needed the code and checked it many times.
