Get in touch with them. Only way to know is to ask the source

I don't think so. There is always a person on the elevator that takes you to 102 and they check your ticket. If it has been already verified, as far as I know, you cannot use it again.

Yes, you have to make reservations separately requesting a day and time your visiting with your city pass #.

I'm sure it will be fine - they're really only interested to know a ticket has been purchased, not the name of the person handing it in. Hope she has a great time!

I don't know the answer to your question, but I made reservations on Tuesday to visit on Wednesday, and all the time slots were still available. There will be more crowds in summer because school is out in the US for summer vacation, and that's when many families with children travel. I read that, to avoid the biggest crowds, visit on a weekday rather than a weekend, and go either early in the morning (it opens at 8:00 or 9:00 AM) or late at night (after 10:45 PM). We went at 9:00 AM, and there was no line. I recommend checking the website every day, and as soon as July reservations are available, make your reservation.

I'm not sure we booked with a city pass

I believe that's with a regular pass.

Tickets are scanned as you enter the building. No one will check the name of the credit card holder.

I do not believe you can alter the flow. Take time to see the museum because you can’t go back after you leave 2.

Hi, I'm sorry I don't know the answer to your question. I would try and phone them (I tried to email them about buying a poster they had ran out of but they blocked my email) When I made enquiries in the shop at ESB, the staff there were most helpful.
