The Eagles face Millwall this evening knowing that victory at The Den will confirm their playoff place with a game to spare.
With Millwall fighting to retain their Championship status, Holloway believes that Palace will need to be on top form to claim three precious points.
He told the Croydon Guardian: "This is going to be a London derby with no room for the faint-hearted. You've got to go over there and do your job and stand up to be counted.
"There's a pride for Crystal Palace in how we do things, and more importantly an overall target of what we want to achieve, which is being one of the four playoff teams.
"It's an unbelievable privilege to still have a chance to go up at this time of year. Realistically, everybody at Palace would have taken that if they could get taken back to this time last year when we were trying to stay up."
Palace have failed to win any of their last eight matches ahead of this evening's London derby.
