Another guest

Julia decided she'd like to try to have another guest of the hotel as the bull. They are the smartest, wealthiest, best looking of the options available. Alas, that decision proved difficult to pull out. Most of the guests at the hotel were there with their wives, girlfriends, lovers, etc. That didn't mean they wouldn't accept, but it would be a rather tough match to find one that said yes. Who'd have to hide it from their partner. Or maybe their partner would want to join in and that wasn't what Julia wanted.

So she focused on those guests she could be sure were there on their own. And she could only spot two. One was hard to miss, he'd been staring at her every time they crossed paths. At dinner or breakfast or at the pool. The other one didn't seem to have an interest on her, but he was a handsome dark-skinned gentleman, tall and surely well hung.

Which one of the guests should Julia approach?
