What happens at the end of Harold and Kumar 2?

They find out it's George W. Bush's house and he comes into the room & finds them. So then they go to some secret room and smoke pot with him. Then they all go to Kumar's ex's wedding( I can't remember her name) & break it up. Her & Kumar get back together and them & Harold go to Amsterdam to meet Harold's neighbor. She's doing a modeling shoot but Harold thinks she found another guy. She explains & then there is some montage of the four of them in amsterdam. Oh & you find that Neil Patrick Harris didn't die at the end of the credits.
