this is a pretty small club, it does get full at times. I don't go through here often, but last week I stopped in for about 10 minutes, no line, went down to my flight, arrived at my gate maybe five minutes later to see my name #1 on the "awaiting seat assignment" list even though I had gotten a seat assignment about an hour earlier (I was doing a SDS), talked to the gate agent, the flight was apparently over weight so they had to undo a few standbys that had cleared.

Anyway, I didn't clear, next flight is 2 hours later. Went back to the club and there were now about 5 people in line (no separate line for F passengers). Agent said "maybe 20 minutes" but it was less than 5.

Is the Centurion "better"? I guess, but it's not better enough to justify dealing with the train there and back.

Some things to watch for:
1) as noted, its crowded
2) the restrooms are outside the club (this seems to really bug some people but you'd have a further walk in many larger clubs, I guess if you find the idea of "sharing" the restroom with USO patrons to be icky then it's a negative)
3) a lot of the seats have those weird side table slab things that make you think they have outlets but they only have them on one side. I'm not really sure how to explain this better but if you need to charge really make sure there are actually outlets before you plop down and unpack all your stuff
4) self service bar, which makes this the BEST club in the country to some people, though the selection is pretty limited
