I said I would report about this when we got here on Wednesday so sorry I am a bit late.
I went to the customer service desk and I asked if I could use the kiosk but was told to get in line. When I got to an agent I asked about the 'Save time' and on line check in I had already complete d and was told that most times the kiosks didn't work and renters have to go to the counter. I handed over our licences and paperwork and there was no attempt to sell me anything.
