Hello dear Nancy,
Thanks for your review! It's great you loved the museum. Regarding the audio tour, we recommend in our communication e-mails to bring your own headphones so you can listen unbothered to the audio tour.
Also, as you said, the pre-paid ticket saves you time from the ticket line.
Please, if there is any other feedback you have regarding the audio tour, feel free to send it to support@cliomusetours.com.
My warm regards,
Angeliki, Product Dept.
