My girlfriend spends intimate time with her male best friend?

My girlfriend's best friend is a male, which I'm totally okay with. However, the friendship appears to be more than a friendship, I think? How should I interpret her friend hanging a photo of just the two of them on his work desk, them travelling to Canada and Florida together (and staying in the same room) and lastly, when she stays with her parents abroad, and he visits (for work), she stays with him in his hotel room. Do I trust her? Or accept it?
