My family along with sisters, their families and parents, are going to Aulani between Christmas and New Years. We are used to all-inclusives so didn't really plan ahead as far as activities and excursions. What extras onsite are ones that we shouldn't miss (assuming it isn't too late to book)? We have children infants-teens. Also any great offsite restaurant recos? We are planning to rent cars at least one day to do the north shore and possibly Pearl Harbor. Are there any great third party excursions that might be good for a large group? Thanks in advance!
