Never use this company, full of cheating, customer service very rude! By mistake I booked two adult tickets at 11:00 PM. On the next day at 2:00 PM (well within 24 hours) I called them to make changes. I was told that I have to pay the penalty of $200 each because it was not on the same day. I was also asked to pay a price difference of $171 each. This means that I need to pay $742 for this change well within 24 hours. I checked their website and found that the new ticket is even cheaper. They explained to me that to change the ticket is different from to book a new ticket. Listen to me, never use this company!
