We've done both breakfasts and my whole family loved CRT much better than Norway- including dd (who was 4 1/2 at the time). We did both breakfasts that year. The food at Norway was not good imo. The princesses were good- good interaction- but no better than what we've had at the castle each time. We did get to see Mulan and that was cool. We've eaten in the castle 3 times- dd thinks it is a MUST- and have had 3 wonderful experiences. Nothing beats eating in 'the' castle to a little girl. DD sincerely believes Cinderella lives upstairs (she is 8 now). I will say, our last trip last Jan. was the best line-up we've had- Cinderella downstairs, Snow White, Jasmine, Belle, and Aurora all upstairs. If dd could pick- those would be her choices- so it was perfect for us. We would like to see Mulan, but dd did not even ask to go back to Norway this trip. The princesses were all friendly and spent ample time with dd and ds. They all started conversation with dd and it was very magical for her (so much so that she teared up when she saw Jasmine). To us, the castle is priceless. It was nice to do Norway once, but the castle is a must for every little girl that believes in the princess magic.
DD loved the castle at 2 1/2- her eyes were wide as saucers when we walked upstairs!
Have you considered doing both?
