I only needed somewhere basic to stay whilst I sat exams at CAA Gatwick. This hotel doesn't take payments using a card machine, it feeds them through a web portal. I had hoped to pay with my phone. After paying online, the hotel insisted it hadn't gone through (and the portal was unclear). My bank app clearly showed a payment, but the hotel insisted I "try again". The following day, I was locked out of my room and still they insisted I "try again" to pay. So I paid twice. No receipt, no invoice.
Please, invest in a card terminal. The hotel is basic, tired-looking, it's fine as a cheap stay but prepare to be charged double and wait for your money-back. I wanted a stress-free stay to assist with my exams - instead I was fretting over payments. Avoid.
