I'm trying to find a 4/6 car rental in Salisbury, near the station, that allows return on Sunday 4/7.
You should insert pick up 6th and drop off 8th, then you will see available cars. Try to avoid out of office ours at city locations. Airport car rental locations are open longer normally.
Do they all have off hour returns? I don't know what the office hours are! I'd think 7am on a Monday, but no. Still trying.
You can always drop off using the key drop box service. But to be able to book a rental vehicle you have to choose the Monday as drop off. It doesn’t effect the price normally.
Finally I got it! Pick-up Salisbury, UK Apr 6 2019 12:00 pm. Drop-off
Salisbury, UK Apr 8 2019 9:00 am. Thank you very much.
