Help Needed Newcastle v. Fulham Tickets Buy on the day or not

[fulhamfever]

Hi All Me and another 2 guys are traveling up from Preston to go watch the match hoping to buy on the day. The tickets show available on the NUFC website in the away end but the Fulham website says dont travel if you dont have a ticket???? Even though the ticket office told me if you show a membership card on the day you will get in and its on General Sale do i need to worry about not getting in or is it just mass hesteria.
