Just be aware that your luggage will not be transferred until around 3 or 4 in the afternoon. If you're going to be in a park all day, it's no big deal, just make sure you keep anything with you that you might need to access.
When I do a split stay, I generally Uber to the new resort with my luggage. Also, I've been told to make sure I go to the desk at the resort I am leaving and physically check out so that I can check in to the new resort. That way, if my room is ready, I can go ahead and take luggage to new room. If it's not ready, I leave my luggage at bell services until I get into my room.
It does take time to do things this way, but I'm not generally a rope drop person and I like having my luggage where I can access it when I want it and not be dependent on waiting for it to be transferred.
