We like to rent the audio guide for our visit in late September. Since we are booking the garden bus tour there isn't an option to book the audio guide for the museum at the same time.
How long is the line for audio guide without reservations? I am a bit concerned that they might even run out of units on the day. Is that possible??!? The bus tour is on at 8:45 am for 45 minutes. So we would start our Museum visit at 9:30 am if it runs on schedule.
Thanks for your help.
