Yes, if you do not use the confirmed tickets, you'll be refunded the ticket amount, not the reservation service fee. No, you can pick up the tickets confirmed under your name just at the date and time specified. We always confirm the date you requested. But sometimes, due to overwhelming demand, the specific time of your visit may be slightly different. This could be 15 to 30 minutes from the requested time.
Every modification is possible.
You new date and time are treated as a new reservation. You only incur another reservation fee, not a second ticket charge. Due to the richness of their contents, each museum deserves no less than two to three hours of your time. The best plan is to visit two museums a day.
