Ok, Faidon poked at it: confirmed that one of the routes coming back from our servers to the hotel network was highly congested and switched priorities to the non-congested route.
Much, much improved. :)

Hi Brion,
such issues may be based on routing, depending of the peerings between the Hilton ISP and Wikimedia. One would need to check both ASes and use the respective looking glasses (does Wikimedia have one?) to check the routes. Many routes are also assymmetrical, so up- and downlink can vary.

I'm seeing verrrrrry slow downloads from Wikipedia on the hotel wifi, on the order of 20-30 kbytes/sec, whereas I get a very respectable 500 kbytes/sec to everywhere else.
