PSB has 2 main seatings. We had a 9:55 PS and we were about the 5th or 6th family in for that seating. They clear out the restaurant after the first seating, replate everything, and then start with the next seating. The fill the restaurant from one end to the other (since we had one of the first seatings of the second "main seating", we were about 6 tables away from the door that the princesses enter from). We enjoyed it a lot, the food was good, and it was not a problem to get refills. We were not rushed by any means, it probably helped that we were seated near the beginning, so after all the princesses came thru, we could relax and eat. The princesses were Jasmine, Belle, Aurora, Mary Poppins, and Snow White. The interaction was very good.
As far as getting to Norway, we were staying at the BC, so we entered thru the IG and walked the path to Norway. The other sections of WS were roped off, you couldn't go past IG or Norway. If you arrive at the main entrance, you would just walk toward Norway and follow the roped off area (there may also be CMs to direct you, but we didn't see any, maybe because we were later). After the breakfast, yes, we headed back to FW, but we only had about 15-20 minutes before WS opened up.
