When you book a Disneyland Paris hotel via the website you also pay for tickets. Can you use the tickets another time or are they date specific? We are wanting to stay 3 nights, but arrive late the first day and leave at 6:30am the last day. So if we book we pay for tickets for 4 days and can only use 2 days. We will be staying in Paris the following week and I wondered if we could return to Disneyland Paris and use one of the day tickets we hadn't used? I hope that made sense. Thanks.
