Disney and several documents online mention when you add the hopper option to your tickets you add them for the numbers of days your purchased tickets. However I've had several reliable folk tell me they've added the hopper option to their tickets for just a single day or two without paying for the hopper option for the entire amount of days they purchase a ticket. For example they were only charged $14 for adding the hopper option to their ticket since they only had one day left on their ticket purchase. So I wanted to get more clarification to see if it's true before I make my plans. We usually don't hop at all, one park per day. However our trip this year is shorter then normal and wanted to split one day in Epcot and MK, but we only need the hopper that one day. Thanks in advance for any help or advice!
