The South London club were ultimately too much for Shakhtar Donetsk, beating the Ukrainians 5-2 on aggregate.
Palace will now face Spanish side Rayo Vallecano, who beat Strasbourg, in the final on May 27th in Leipzig.
Speaking to TNT Sports after the game, Glasner insists his side will be giving their all against Everton, although his players have been given time off to “enjoy themselves.”
"I just gave them tomorrow off. We had a bad experience after the first leg against Shakhtar, we trained the next day and they weren't sharp,” he said.
“Maybe this will help when they are out somewhere in London.
"I said to the players that we won't wave the white flag against Everton but I think it's important they enjoy themselves, rest and we will meet on Saturday to prepare for Everton. It's about getting everything planned in the right way.”
