I can recommend the GWU637, with caveats. I spent 3 months in a hotel wrapping up a contract and starting a new job where the hotel wi-fi hated my Mac. Phone - fine. Tablet - fine. Mac? Might as well not have existed. It runs pretty hot and there's no 802.11ac support but often when you need this, that isn't an option anyway. There's an undocumented /menu.asp page that you're almost certainly going to need for anything other than a 192.168.1 network.
