We have just come back from Florida - used the kiosk with no problems. It found my details from the savetime but I had to re-enter my husband's driving license details. For some reason it doesn't like Bedfordshire as a county so I left it blank - that worked out fine and it went through. The first time I used it, I printed off the instructions which are linked to above - the pictures make it very easy to follow when you're tired and a bit confused.

We saved masses of time as there was a huge queue but I also like the fact that you don't risk being 'upgraded' to something that costs you money without realising - the option is still there but it is very clear what the extra costs are on the kiosk. We had a sat nav with the car this time and you can still use the kiosk and get the sat nav at the exit barrier as you leave the garage.
