I hope this is the right place to ask, and I know this may be an easy question for most. My mom has a package for 4 nights at Boardwalk Inn with free dining and a 5 day park hopper. She added a night, without the free dining, and I would like to know is she can add a day to her ticket when she arrives at the resort or does she do this before her arrival?
