My son (just did this past Spring) flew in the day before and was so happy he did. He had "met" lots of kids on facebook before going, and they had arranged a meet at downtown disney the night before. So going in, he knew alot of kids already. Also, it gave him a rested nights sleep before the first long few days, he got up and cabbed it over from Pop Century, very easy. Have a blast, he loved every minute of it (did Great Movie Ride, still doing it in fact, just finished the Halloween weekend going "seasonal").
