I have used Disney Floral and gifts before. Prior to Covid, we had items delivered to our room and another resort/room. When making the reservation I had the reservation number(s) of the other group in our party and provided their name as well. The items were delivered to our room at AoA and our in-Law's room at WL as scheduled and were a fun surprise for all.
We are going back soon, and I recently placed an order for a family that is traveling with us. Because of COVID restrictions, Disney F&G will deliver to the resort, but the guests will need to come and pick up their items from the front desk. Not sure when you are looking to place your order, but I will try and report back next week on how this worked, including how the other family was notified.
