We used these tickets for our quick trip down for Easter.
They are good for 4 days of hopping in the parks, and expire 14 days after the first use.
They had only one down side for us. We felt compelled to go into the park on the 4th day, even though we slept late and had to leave early for the airport. It it had been a regular hopper, that never expired, we might have been more apt to relax and do a little shopping, then go to the airport, but we felt we had to "get our money's worth."
