I stayed in San Francisco for a week. I went to MOMA for the first time with a voucher. If you go to MOMA, you will not have to go to the City Pass Voucher Exchange to exchange your Voucher A4 paper for a City Pass. When you go to the place you want to use, you can tear off one by one each time you enter and use the 3-day Muenpas Pass. Only the City Pass was shown to the bus driver during the bus ride, but it was used more than three days because it could be used during the entire trip. You can use it within 2 ~ 3 days as hard as you can, and Hover is recommended.
