Well that's LGA for you. I wouldn't wish a visit to that airport on my worst enemy, except for the Marine Air Terminal, that place is a gem. Still bums me out that DL's shuttle flights got moved to the main terminals. I had a LGA visit earlier this year where it took nearly an hour just to get off of airport grounds and another two to get to midtown. Sometimes you just have to laugh at the absurdity of it.

Glad you got to experience both for comparison though. I've only made it to the LGA Centurion once, I wasn't particularly impressed, but I had also just been at the DFW Centurion lounge which I personally think is the best of the group.
