Planning our second trip for early December 2018. The last time we went, my oldest daughter and niece were 17/16 so we let them explore the parks on their own - even visited different parks using Mickey transportation. This time my twins will be newly 14 when we go. Right now, they do no have phones. Would you let reasonable behaved teens go on their own? I am more inclined of having them do a ride or two and then meeting us at a point and going from there. We have one other younger one, who will be 10 at the time and will be with one parent at least.
