Well, I would just point out that one person's experience is not everyone's. In November, we had the same scenario and the CM said she had to wait until she got phone approval. Well, phone approval did NOT come before park opening. So, we just had to get around to Norway as everyone else was entering.
The good news for us was that once we got to Akershus, they got us in quickly and actually "cut" us through the line to get pictures with Belle.
My suggestion is to not stress too much, just let things happen as they will and trust that things will work out along the way.
