Once they arrived, everything went by pretty normally.
As Kyle wasn't a known figure in this part of the world, it was quite easy to move about on the first day. Kyle figured that things may get slightly more 'hectic' once the interview was done, but even then, it wouldn't be too bad.
So why the precautions on having Edward take his place?
Simple.
There was too much at stake to take things for granted.
He would rather be overly cautious than be caught unawares. Having Edward take his place meant that he would have an alibi while he did his mission. Even though it would seem far fetched i.e. how would anyone ever think Kyle would be connected to what he was going to be doing next?
Call him paranoid, but Kyle would rather not take the risk - even if the risk was minute.
To minimise the risk even more, Edward did not make any contact with them. Except for that night, of course, when Kyle slipped over to his room undetected.
