I would assume that with a guy like Fleury -- who's been on a yo-yo -- there is some communication from the team. For example, RBA may pull him aside and say, "we're sending you back to Charlotte for All-Star weekend so you can get game action, but you'll be back for practice on Monday," so Fleury can schedule things. I'm fairly certain the players aren't learning about recalls and getting sent down the same time we are when the transaction comes across Twitter.
I know we've had conversations before about how a player can be in Raleigh in time when the transaction just happened at 3 p.m., but it's likely that the player was told the night before or early in the morning, and the actual transaction was not urgent.
I'm sure they also have rooms on permanent reserve at a local hotel for situations like these.
It's really just the actual transportation that I wonder about.
