Hi again Beth Ann! Judging by last spring's prices, there's a good chance that the rates for playing on the Disney
golf courses will be lower than the ones currently on the site when you take your trip. Generally the rates have dropped a bit starting in Mid-May. In fact this past year, Disney offered a Summer Price Slice special with rates significantly lower than the current ones if you were flexible with your tee times.
How fun that your mom and daughter are planning to dine with royalty during your trip! My own daughter loves meeting the princesses, so a meal with them is always on our schedule too! If your daughter enjoys dressing up, be sure she wears her princess gown and tiara to Akershus! The end of your question was cut off, so if you wanted to know something specific about Akershus, or anything else, feel free to write me again!
Wishing you a magical vacation in May! Come see me again at the Moms Panel if I can help you plan your trip!
