What is the difference between pick up in terminal vs on airport vs free shuttle bus?
In terminal, the desk is inside the terminal.
On Airport, in the facilities of the airport, normally at the car parking.
Shuttle bus is a free service that some suppliers “on airport" offer to their customers so they do not need to walk to the office/counter.
But, in the case of Krabi, as it is a very small airport, there is very little difference between a supplier that is located “in the terminal" and another that have its location "on the airport".
So there are counters in the airport, right ?
Yes there are.
Do I have to show the confirmation document at the counter?
After ordering a car, you will receive an email with the confirmation voucher. Print and present this at the counter, all the information is contained on there.
