My sister and her family won 4 1 Day Park Hopper tickets. Can we just add days to these? Does this cause a problem for free dining. There are 13 of going on this trip and we are just trying to figure out whats the cheapest way is incorporate those tickets among us. We are staying for 8 nights and getting a 5 day park pass, some of us will be use park hopper some will not. Thoughts?
