This might get posted twice; wi-fi at this hotel is horrible.

Ended up taking shuttle, as it was right on the "border" (mid 40's and I had a suitcase). White Castle looked to be about 2 long blocks from Holiday Inn, with a BK and McDonalds between WC and hotels. Saw zero (0) people walking around that area, and it was unclear if there was a continuous sidewalk, but looked pretty "normal" in that I would have attempted to walk from Hotel to White Castle after unloading luggage if it hadn't started to rain.

Ended up eating horrible take-out from TGIF while watching Bourdain eat Iberian Ham on TV.

ObFTInfo:

Door #2 to red shuttle bus ("Midway Hotel Group" or something like that), comes every 20 min.
