terrible idea and system to buy priority security. slow awkward and cumbersome, at least add paypal payment method. typically the only time i need it is when i arrive and find a massive que which isn't that often. so when i arrived monday to find a massive que having to do it via website with dredit card on my phone in the hall took nearly as long as waiting in the big que. it was hassle enough when the machine was there and it was credit card only, it should have been cash or card. now that its online its a complete pain. please at least revert to the old system as an option to buying online as this system is just not user friendly.
