He'd have to be a stark raving mad lunatic to have deliberately planned to stab a girl to death in his OWN hotel room. And I can hear you all saying "he is". But he's not that stupid.
I think it was a coincidence.

The hotel room where Flores was found was registered in van der Sloot’s name, he said.
A hotel guest and an employee witnessed the pair entering the hotel room together at 5 a.m. on Sunday, Guardia said.
Police have video of the previous night, May 29, of van der Sloot and Flores together at the Atlantic City Casino in Lima, he said.
According to immigration officials, van der Sloot fled to Chile over land on Monday, Guardia said.
“We have all the evidence to show that the killer is this man,” the victim’s father, businessman and race-car driver Ricardo Flores told CNN en Español.
Ricardo Flores said that police found his daughter’s car about 50 blocks from the hotel, and that inside, they found pills like those used in date rape cases.
I don't think it was.
It's clear that Joran likes to prey on young women who are partying at the end of the school year.
He probably figured that he could pull off another rape/murder without too much trouble.
However, he probably encountered obstacles he did not anticipate and had to decide to either risk dumping the body and getting caught red-handed or to flee.
He chose flight and left the body behind.
I am sure that his intention was to kill her bloodlessly and to safely dispose of the evidence - not to leave a bloody corpse in his room.
Things clearly did not go according to plan.
What if this was his F U anniversary to the world? What if he LIKES being the murderer of the decade?
