We were there March 24-30. We got a PS ahead of time for Easter breakfast, but it wasn't crowded when we got there. While there we got a PS for Saturday night at 5pm from guest services at 3pm the same day. We also just walked in for breakfast once. If you go towards the beginning of the meal you probably will just be seated, but if you want to be sure you could make some Ps's... Don't miss the breakfast...blueprint omlette....mmmm mmmm mmmm.
